Standard Replacement Exhaust Catalytic Converter for Porsche Boxster 986 2.5L



Porsche Boxster 2.5L Replacement Cats made in grade 409 stainless steel. Recommend to change in a pair

Fits:
Porsche Boxster 986 2.5L

A catalytic converter is an emissions control device to stop harmful exhaust gasses from entering the atmosphere. In 1993, they became legality in the UK as part of the Euro Emissions standards. The aim of them is to improve air quality. As emissions standards have become more stringent the number of cats on a vehicle has increased. Many vehicles now have two or more to enable them to meet the Euro Emissions standards.

Our cat is made up of the following components:

• Ceramic monolith of a honeycomb design to allow free air flow and maximum surface area, coated with precious metals to enable the conversion of gasses that pass through it
• Interam matting to hold the monolith in place. The matting expands when exposed to heat to supply the pressure needed to keep the monolith secure
• A grade 409 stainless steel can (or housing) to provide protection and enable the cat to be built into the exhaust system. 409 grade can contain upto 90% iron and will be prone to rust. It still has higher rust-resistant properties than mild steel.

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.
