Porsche Macan 2.0T 2016-2018  - SOUL Resonated Muffler Bypass Exhaust

SOUL’s mandrel bent 2.5″ rear system offers a refined increase in shift barks, burble, and engine tone while minimizing drone with high flow race resonators.

• Fits all Porsche Macan 2.0T vehicles (2016+)
• Increases the desirable spectrum of engine notes and tone while minimizing drone with race resonators
• Weighs approximately 13.9 lbs / 6.3 kg less than factory exhaust components (34.4 lbs vs 21.15 lb)
• Designed and built in-house at our Willow Grove, PA facility
• All Soul Performance Products are backed by an industry leading Lifetime Warranty for both street and track use

DEVELOPMENT AND TESTING:
The Porsche Macan 2.0T is impressively refined from the factory, with extensive sound insulation and heavily muffled exhaust flow. During development, SOUL’s engineers found that the OEM midpipes were already smooth and high-flowing — but the rear mufflers restricted performance and character. The SOUL Resonated Muffler Bypass Exhaust replaces the factory mufflers with a lightweight, clamp-on 2.5-inch straight pipe design, incorporating race resonators to reduce cabin drone while maintaining an aggressive exhaust note. This straight-through resonated system unlocks additional turbo and engine sound under acceleration while keeping cruising noise civilized. The Y-pipe configuration exits through quad tips, optimizing exhaust distribution and allowing adjustable tip alignment for a flush or staggered appearance.

SOUND:
Expect a refined but assertive exhaust tone, with sharp bark between shifts and subtle burbling on deceleration. Under full throttle, turbo spool and engine sound become more pronounced, while backing off returns to a composed tone. In Comfort mode, a faint drone may occur during high-gear cruising but is easily managed by engaging Sport mode or downshifting.

CONSTRUCTION: 
Each SOUL Resonated Muffler Bypass system is handcrafted in-house from mandrel-bent, .065" thick T304L stainless steel tubing. Every assembly is back-purged TIG welded using premium ARCAL™ Prime argon gas to ensure complete weld penetration and exceptional longevity. The integrated straight-through race resonators feature full metal packing for maximum durability and consistent tone. Fixtures are made from thick-gauge aluminum to prevent distortion and guarantee perfect fitment.

BOLT ON AND GO:
Each system undergoes a strict quality inspection before being foam-packed for safe delivery. Installation involves a clean cut at a factory-marked break point, allowing easy reinstallation of the original exhaust if desired. Detailed instructions are included for a smooth DIY installation, and valve simulators are provided to prevent check engine lights.

LIFETIME WARRANTY:
Drive with confidence — all SOUL Performance Products are covered by a Lifetime Warranty for both street and track use. The SOUL team stands behind every exhaust system, ensuring long-lasting reliability and customer support.

Porsche Macan 2.0T  -  SOUL competition downpipe

Unlock extra turbo sound, flat four aggression, and increased response with a bolt in catalytic converter delete downpipe for your Macan 2.0T.

• Fits all Porsche Macan 2.0T vehicles (2016-2018)
• All Soul Performance Products exhaust components are backed by the industry’s best Lifetime Warranty for both street and track use

DEVELOPMENT AND TESTING:
The Macan is rather quiet in factory format. Eliminating the restrictive factory catalytic converter adds to drivability and also unlocks the sweet sounds of the turbo with a major increase in snarling and crackles from the exhaust. The sound is aggressive without droning in the cabin. Smooth mandrel bent piping encourages better throttle response and a more exciting exhaust note. Easy to bolt in with no modifications required, this is a great, reversible solution to make your Macan more exciting.

CONSTRUCTION: Each downpipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked.

BOLT ON AND GO:
Every downpipe is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition.. New hardware is included.

CHECK ENGINE LIGHT?: This product may trigger a check engine light due to removal of the factory catalytic converter. We suggest a custom ECU tune to disable any check engine lights (for track use only).

LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.

NOTES
+ This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road / competition use only due to removal of factory catalytic converters
+ Boost spikes can occur as a result of increasing the exhaust flow with a catless downpipe. We highly recommend an ECU tune to not only extract maximum power from this mod, but to have the best possible drivability as well

Porsche 981 Boxster / Cayman PDK  TRANSMISSION -  SOUL Race Exhaust System. 

SOUL’s Race Exhaust System is designed for aggressive track use and built around maximum durability, lightness, and performance.

• Fits all Porsche 981 Cayman / Boxster vehicles (2013-2016) PDK TRANSMISSION, with factory or SOUL headers (differences in tolerances from other manufacturers can create issues with over axle pipe clearance)
•  Designed and built in-house at our Willow Grove, PA facility
•  System weighs approximately up to 18 lbs / 8.1 kg less than factory exhaust non-PSE components ( 30 lbs vs 44 lbs non-PSE / 48 PSE with mounting brackets included)
•  All Soul Performance Products components are backed by a renowned Lifetime Warranty for both street and track use

DEVELOPMENT::
Our mission was to engineer a lightweight, durable, and cost-effective race exhaust system for the 981 Boxster and Cayman—one that delivers proven performance, reliability, and accessibility for serious track enthusiasts. By collaborating with respected shops, technicians, and seasoned drivers who have conducted their own independent testing over the years—including special thanks to Bryan Schute at Speed Sport Tuning and the teams at LN Engineering / BRS—we developed a track-bred system designed to meet the demands of competitive driving.

PIPING:
The system features full 2.5” over-axle piping, carefully profiled to provide sufficient clearance for axles and sway bar end links—even on aggressively lowered or heavily modified vehicles.

BESPOKE BRACKETS & MOUNTS:
Traditional welded hangers and brackets are prone to failure under the rigors of racing—a failure that can end a track day instantly. To solve this, SOUL designed a reinforced mounting solution that sheds over 5 lbs compared to the OEM setup, while remaining modular and easy to repair or replace after a track incident.
The forward piping connects to a custom SOUL transmission mounting brace—engineered for both manual and PDK models—via heavy-duty Mikalor band clamps. Additional rubber vibration dampeners support the over-axle piping, minimizing stress from flex and vibration across the system to ensure long-term durability under extreme use.

CONSTRUCTION:
Each system is handcrafted in-house by our skilled fabrication team using mandrel-bent .065″ wall, 2.5″ diameter T304L stainless steel tubing. Brackets are laser-cut, press brake-formed, and TIG welded for maximum strength, while all welds are back-purged to ensure long-term durability under the most extreme racing conditions.

SOUND:
This system is designed with track performance as the priority, not sound suppression. It is extremely loud, and even with resonators, some drone will be present. We do not recommend pairing this exhaust with aftermarket headers for street use. At wide-open throttle, however, the sound is nothing short of exhilarating—raw, aggressive, and unmistakably motorsport. For a more balanced option suited to daily driving, we suggest our Valved Exhaust System.

BOLT-ON INSTALLATION:
Every exhaust is rigorously quality-checked and fixture-tested to guarantee perfect fitment. Systems are securely foam-packed for safe delivery and include all-new high-grade hardware for the header-to-exhaust flanges. Thorough instructions are provided, making installation straightforward for most DIY enthusiasts.

Porsche 981 Boxster / 981C Cayman SOUL Performance Exhaust System

High quality mufflers offer a refined, sporty tone with minimal drone. Gain the enhanced response, character, and sound that your Porsche deserves.

•   Fits all Porsche 981 Boxster / Cayman models (2013–2016)
•   Direct bolt-on installation with included instructions
•   Choice of multiple exhaust tip styles and finishes—or customize your own

•   Covered by SOUL’s Lifetime Warranty for street and track use

DEWELOPMENT:
Following the success of our Valved Exhaust and its ability to fight drone, we wanted to offer a lighter, valveless version that offers an invigorating exhaust note (just like valves open mode on our Valved Exhaust) at all times with the least amount of undesirable elements like droning and rasp. This system is perfect for those who crave an aggressive sound to pair with aftermarket headers and not have it be overbearingly loud. The volume level is delightfully greater than that of PSE (Porsche Sport Exhaust) with valves open while retaining a refined exhaust note. This system is also beneficial for track cars looking for maximum flow in an exhaust but must mind decibel readings. The mufflers are incredibly effective at minimizing drone and encourage a fuller, more robust tone befitting of a Porsche.

CONSTRUCTION:
Each system is constructed from mandrel-bent T304L stainless steel tubing, including robust 2.5″ over-axle pipes, and paired with mufflers reinforced for maximum durability. SOUL mufflers are packed with premium sound-absorbing material engineered to withstand long-term use without breaking down or blowing out.
For a personalized look, select from a wide range of 321 stainless steel exhaust tips in various styles and finishes—or work with us to create a fully custom set. For those seeking performance advantages, titanium single-wall tips are also available, offering the same striking appearance while saving nearly a pound of weight compared to stainless steel.

BOLT ON AND GO:

Porsche 981 Boxster / 981C Cayman SOUL Valved Exhaust System

The factory exhaust system on the Porsche 981 Cayman and Boxster is bulky and restrictive, muting both performance and sound. The SOUL Valved Exhaust System is designed to free the car’s natural character by reducing weight and incorporating a precision valve system that delivers a dramatic transformation in responsiveness, tone, and driving enjoyment.
With the valves closed, the system produces a refined, sporty exhaust note with zero drone—perfect for comfortable daily driving and discreet neighborhood entries. Open the valves, and the flat-six engine comes alive with an intoxicating motorsport-inspired soundtrack, ideal for spirited back-road drives or track sessions.

•   Fits all Porsche 981 Boxster / Cayman models (2013–2016)
•   Direct bolt-on installation with included instructions
•   Choice of multiple exhaust tip styles and finishes—or customize your own

•    Valve controller kit included – necessary for cars without PSE and optional for cars with PSE to provide manual valve override
•   Covered by SOUL’s Lifetime Warranty for street and track use

DEWELOPMENT:
We wanted to be certain that our system offered a superior spectrum of sound – Cup car inspired with valves open but with a refined, no droning tone with valves closed. The SOUL mufflers practically eliminate droning – even with aftermarket headers the sound is reserved in the cabin with valves closed!

CONSTRUCTION:
Each system is constructed from mandrel-bent T304L stainless steel tubing, featuring 2.5″ over-axle pipes, and equipped with mufflers built with reinforced casings for long-term durability.
•  With the valves closed, exhaust gases are directed through SOUL’s high-quality mufflers, packed with premium sound-absorbing material engineered to withstand heavy use without breaking down. These mufflers are highly effective at eliminating drone, channeling gases through perforations into the outer piping for a smooth, refined tone.
•  Open the valves, and exhaust gases flow freely through the large 2.5″ straight-through piping, while the perforations allow the exhaust to interact with the muffler—producing a deeper, fuller, and more aggressive sound that captures the true character of the flat-six engine.

TIPS:
Choose from a variety of tip styles and finishes, ranging from sleek single-wall 321 stainless steel to premium double-wall chrome. For a personalized touch, logo engraving and custom tip colors are available upon request. For those seeking performance benefits, lightweight titanium single-wall tips are also offered—shedding nearly a pound compared to stainless steel options.

BOLT ON AND GO:
Each exhaust system undergoes rigorous quality checks and fixture testing to guarantee precise fitment. Every kit includes detailed installation instructions, making the process straightforward for most DIY enthusiasts. Valve operation integrates seamlessly—controlled via the factory PSE button, included valve controller fobs, and even compatible with HomeLink for added convenience.

DEVELOPMENT:
For the 981 platform, we engineered a system with properly sized 2” runners and optimized collectors to unlock maximum power from the 3.4L engine, while still delivering impressive gains on the 2.7L. We selected high-flow catalytic converters sized for both performance and durability—avoiding the compromises of smaller, cheaper alternatives. The result is a superior exhaust that delivers a broad spectrum of sound: valves open reveal a CUP car–inspired roar, while valves closed provide a refined, drone-free tone. Thanks to SOUL mufflers, even with aftermarket headers the exhaust remains composed and reserved when the valves are shut.

CONSTRUCTION:
Our headers are precision-engineered and crafted from T304L stainless steel for strength and performance. Featuring port-matched flanges, smooth-radius primary tubing, and optimized collectors, they deliver maximum exhaust flow and power gains.

Porsche 986 Boxster 2000-2004 SOUL Competition Exhaust Package

The SOUL 986 Competition Exhaust Package upgrades the restrictive factory system with a precision-engineered header and exhaust setup, boosting power while delivering an aggressive yet refined Porsche sound.  

•  Compatible with all Porsche 986 Boxster models (2000–2004)
•  Backed by SOUL Performance Products’ Lifetime Warranty for both street and track use

DEVELOPMENT:
The Porsche 986 Boxster is a fantastic sports car with huge potential, but its factory exhaust is overly restrictive. Stock headers use oversized catalytic converters, thin flanges, and crushed primary tubing that hold back performance, while the OEM exhaust adds a second set of converters that further reduce power. The SOUL 986 Competition Exhaust Package eliminates these weak points with a complete header and cat-back system engineered to work together. Designed to maximize performance and sound, the system delivers excitement without unwanted drone—SOUL mufflers keep things reserved at partial throttle, even when paired with catless headers. No valves are needed, making it the perfect choice for drivers who want raw performance and a bold exhaust note on demand, yet comfortable refinement around town.

CONSTRUCTION:
  Our headers are precision-engineered and crafted from durable T304L stainless steel, featuring port-matched flanges, smooth-radius primary tubing, and optimized collectors for maximum exhaust flow and power gains. Each system is mandrel-bent from T304L stainless steel and paired with mufflers reinforced for long-term durability. Custom brackets and clamps are supplied for a secure installation on your Boxster. To finish the look, select from a range of 321 stainless steel exhaust tips in various styles and finishes—or work with us to create a fully customized set.
  
BOLT ON AND GO:
Every exhaust component undergoes strict quality checks and is fixture-tested to guarantee perfect fitment. Each system is foam-packed for safe delivery and comes with new high-grade hardware for the header-to-exhaust flanges. Comprehensive installation instructions are provided in the box—see the notes at the bottom of the page for details.

CHECK ENGINE LIGHT?:
This product may trigger a check engine light due to removal of factory catalytic converters. O2 Spacers are available to reduce any chances of triggering a CEL. We suggest a custom ECU tune to disable any check engine lights (for track use only).

LIFETIME WARRANTY:
Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.

NOTE:
+  This package is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for closed course competition use only
+  Trimming of the inner fender liner and exhaust heat shield is required on all vehicles and headlight auto leveling sensor may need to be disabled / removed and rerouting of brake hard line may be necessary to protect from heat – as such we recommend professional installation. Contact us if you need a dealer / installer recommendation
