Porsche 981 Boxster / 981C Cayman SOUL Competition Exhaust Package

The Soul Performance Products Competition Package for the Porsche 981 Boxster and Cayman is engineered by enthusiasts, for enthusiasts. By combining the superior flow of SOUL Competition Headers with the x-pipe efficiency of the Valved Exhaust System, we’ve created the ultimate balance of performance, sound, and drivability—perfect for both street and track use. With the valves closed, the exhaust note remains refined and comfortable, ideal for daily driving without fatigue from excess volume or drone. Open the valves, and the system unleashes the flat-six engine’s raw character—delivering an intoxicating, aggressive symphony that commands attention as it exits through your choice of stylish exhaust tips.

Package Includes:
•   SOUL Performance Products Valved Exhaust System
•   SOUL Performance Products Competition Headers

•   Direct bolt-on installation with included instructions
•   Wide selection of tip styles and finishes, with custom options available  
•   Covered by SOUL’s Lifetime Warranty for street and track use

POWER:
Testing was conducted on a Mustang Dyno using a vehicle equipped with race headers, a Porsche Sport Exhaust System, and a custom tune as the baseline. With the Soul Performance Products Competition Package installed, the car gained 11 wheel horsepower and 9 ft-lbs of torque—with the potential for even greater gains when paired with a custom retune.

CONSTRUCTION:
Our precision-engineered headers are crafted from premium T304L stainless steel and designed to deliver maximum performance. Key features include port-matched flanges, smooth-radius primary tubing, and collectors optimized for efficient exhaust flow—all working together to unlock proven power gains.
Each system is mandrel-bent from T304L stainless steel tubing, fitted with mufflers reinforced for long-term durability, and thoroughly inspected before shipping to ensure uncompromising quality. For the finishing touch, choose from a wide selection of 321 stainless steel exhaust tips in various styles and finishes—or contact us to create a fully customized set.

BOLT ON AND GO:
Each product is fixture-tested to guarantee a precise fit, then securely foam-packed to ensure it arrives in perfect condition. Detailed installation instructions are included, making the process straightforward and achievable for most DIY enthusiasts.

LIFETIME WARRANTY:

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

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:
Each exhaust is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.

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 questions or issues that you may have.

Porsche 986 Boxster SOUL Spec Race Exhaust

Unlock the full potential of your 986 Spec Boxster with a race-bred exhaust engineered for maximum durability, reduced weight, and proven performance. Designed specifically for competition use, this system delivers the strength and sound demanded on track while shedding significant weight over factory components.

•  Fits Porsche 986 Boxster Base vehicles with 5-speed manual transmission (1997-2004)
•  Weight savings: 24.8 lbs / 11.2 kg lighter than stock (14.7 lbs vs. 39.5 lbs)
•  Precision-built in-house at SOUL’s Willow Grove, PA facility
•  Backed by SOUL Performance Products’ Lifetime Warranty for both street and track use

DEVELOPMENT:

Several Spec racing teams and shops including our development partner, Brandywine Motorwerks, have been seeking an exhaust solution that is durable enough for racing use as existing systems on the market and DIY solutions have been known to fail. We set out to build the most durable system possible while being cost effective and minding weight. A lack of resonance damping in a 986 exhaust system for competition use can cause metal fatigue in the factory headers, resulting in cracking. We crafted bespoke, adjustable brackets to mount the exhaust to the transmission to match movement of the drivetrain to the exhaust opposed to hard mounting to the body. Silicone dampers are also included as part of the brackets to help absorb vibrations. Clamps are not welded to the piping to prevent fatigue and provide easy / efficient replacement – the only welds in the entire system are in the flanges to the headers and every weld is back purged for maximum weld strength and durability. The brackets are adjustable for the best possible fitment and the rear pipes are easily replaced in the event of collision damage. 2″ straight piping keeps exhaust velocity high and weight down. Sound attenuating components like resonators are decidedly absent to reduce weight and complexity as PCA Club Races are not hosted on sound limited days. Should decibel limits be considered for other competition series or HPDE events on sound restricted tracks, alternative solutions can be used. The end result is a race bred system that will hold up to the stresses of racing and last until you podium – and beyond.  

CONSTRUCTION:
Each system is made in-house by our fabrication team from mandrel bent .065″ wall, 2″ diameter T304L stainless steel tubing and laser cut brackets. All welds are back purged for increased longevity under the most extreme conditions.

BOLT ON AND GO:
Each exhaust component is rigorously quality-checked, tested in a fixture to ensure perfect fitment, and then foam packed to ensure it arrives in perfect condition. New high grade hardware is included.

CHECK ENGINE LIGHT?:
This race exhaust will trigger a check engine light due to removal of factory catalytic converters and deletion of the secondary o2 sensors. If this is bothersome, some race shops servicing SPB cars recommend turning off the CEL via removal of the CEL bulb.

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 exhaust is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for closed course competition use only.

Please note: This item is not a stock product. It is a special order part and once ordered with us is not subject to cancellation or return unless proven not fit for purpose or defected.

With valves closed, the system offers a smooth, drone-free tone ideal for daily driving. Open the valves, and the flat-six unleashes its full roar through a straight-through flow path, exiting via exhaust tips in the style and finish of your choice. Built around large-diameter runners and high-flow catalytic converters, the headers maximize flow while enhancing that signature Porsche sound. Every system is backed by our industry-leading Lifetime Warranty, giving you confidence both on the street and at the track.

Package Includes:
•   SOUL Performance Products 981 Cayman Valved Exhaust System

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. Each system is mandrel-bent, fitted with reinforced muffler casings for durability, and rigorously quality-checked before shipping to ensure the highest standards.
