NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.

For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.

 If you are located outside the UK, please check your local laws and regulations to ensure compliance.

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

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.

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.

Porsche 986 Boxster 2000-2004 SOUL Street Exhaust Package

The SOUL 986 Street Exhaust Package upgrades your factory system with a precision-engineered header and exhaust setup that boosts power while delivering an aggressive yet refined Porsche sound. Premium high-flow catalytic converters ensure clean performance without triggering check engine lights.

•  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 offers excellent performance potential but suffers from a restrictive factory exhaust. The stock headers use oversized catalytic converters, thin flanges, and crushed primary tubing that limit flow, while the OEM exhaust adds a secondary set of converters that further choke power. The SOUL 986 Street Exhaust Package addresses all of these weak points with a complete header and cat-back system engineered to work in harmony. Designed for performance and sound balance, the system boosts excitement without introducing unwanted drone—SOUL mufflers keep the tone refined during partial throttle, even when paired with aftermarket catless headers. No valves are needed; the result is a system that’s loud when you want it to be, yet comfortably reserved around town.

CONSTRUCTION:
Our headers are crafted from premium T304L stainless steel and engineered for maximum performance. With port-matched flanges, smooth-radius primary tubing, and optimized collectors, they deliver improved exhaust flow and noticeable power gains. Each set is mandrel-bent, rigorously inspected, and fitted with mufflers featuring reinforced casings for long-lasting durability. Merge spikes further enhance flow efficiency at the collector, while a range of 321 stainless steel tip styles and finishes—or fully customized options—let you tailor the perfect look for your Porsche.

BOLT ON AND GO:
Every exhaust component undergoes strict quality checks and is test-fitted in a fixture to guarantee precise alignment. Each system is foam-packed for safe delivery and comes complete with new high-grade hardware for the header-to-exhaust flanges. Detailed installation instructions are also included for a smooth, hassle-free setup.

About Sport Silencers / Mufflers

Porsche Sport Silencers & Mufflers - Performance Sound & Exhaust Upgrades

Sport Silencers / Mufflers are designed to enhance the sound, performance, and driving character of your Porsche by improving exhaust gas flow and delivering a more engaging exhaust note. Compared to standard exhaust silencers, sports mufflers reduce restriction, sharpen throttle response, and provide a sportier tone that better reflects Porsche’s performance heritage.

Available from Design911, this category includes both genuine Porsche sport exhaust components and high-quality aftermarket performance mufflers, giving owners the choice between factory-engineered authenticity and performance-focused customisation.
