This sports centre sections is a direct bolt on replacement, you don't even need to removal of bumper, Proprietary megaphone design- mandrel bent tubing which saves 14 lbs over the stock center section ( GT3 , RS with Ti center muffler saves 5 lbs )
Sport button remains fully functional for every day use, absolutely NO modifications. This system offers a deep aggressive exhaust note over the Porsche stock system the factory primary mufflers, catalyst and exhaust flaps are all retained
The DesignTek Sport Center Section system is a direct bolt on replacement center section which reduces weight, improves sound and offers a mild increase in performance. Porsche has done a wonderful job with the design and manufacture of the factory system with virtually no improvement to be made by installing a complete (mufflers, headers and cats) aftermarket system.
Direct bolt on replacement center section with dual 3.5 stainless tips (factory offers dual 3"). The system is made of mandrel bent T304 stainless tubing which is TIG welded and features a proprietary megaphone design to improve sound in the upper RPM range. The system saves over 14 lbs of weight over the stock ( stock gt3) and (5 lbs over GT3RS with Ti muffler), power is up 3-5 hp on average and now the sound is finally worthy of this magnificent engine.

Rear silencer including reduced cell catalytic converter

Fits:
Porsche 997 GT2 and GT2 RS 2007-2012
The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual
RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector
ECU REMAPPING - ENGINE LIGHT
Replacement or removal of components such as catalytic converters, GPFs and electric actuators may cause the engine warning light to come on. In this case, the installer must reprogram the software to eliminate the light

Standard Exhaust Systems – Engineered for Performance, Sound & Longevity
A standard exhaust system is essential for your Porsche’s performance, efficiency, and sound. It controls the flow of exhaust gases from the engine, reduces emissions, manages noise levels, and ensures balanced back pressure for optimal power delivery.
At Design911, we supply standard exhaust systems built from high-grade stainless steel and corrosion-resistant materials. Designed to meet or exceed manufacturer performance standards, these systems deliver the perfect blend of durability, refinement, and performance — ideal for both daily driving and restoration projects.
Each exhaust system is developed to ensure precise fitment, excellent gas flow, and an authentic Porsche exhaust note that retains the car’s original character.
What Do Standard Exhaust Systems Do?
A standard exhaust system performs several vital roles that keep your Porsche running efficiently, cleanly, and safely.
Core Functions:
- Directs
exhaust gases safely away from the engine.
- Reduces
emissions through catalytic converters and silencers.
- Controls
back pressure for balanced performance and fuel efficiency.
- Minimises
engine noise while preserving Porsche’s signature tone.
- Aids temperature regulation and exhaust scavenging.
A properly maintained exhaust system ensures smooth performance, reduced fuel consumption, and compliance with emissions regulations.
Why Do Exhaust Systems Fail?
Exhaust systems are constantly exposed to heat, moisture, and corrosive gases — all of which take a toll over time.
Common Causes of Failure Include:
- Corrosion
and rust from road salt, condensation, and moisture.
- Cracked
welds or pipes due to vibration and thermal cycling.
- Internal
baffle damage causing rattling or loss of silencing effect.
- Blocked
or leaking joints leading to reduced performance and increased noise.
- Burnt-out catalytic converters or mufflers reducing efficiency.
Signs of exhaust failure include loud noises, rattling,
exhaust odours, or reduced engine performance — all clear indicators that
replacement is required.
Why Replace Standard Exhaust Components?
Replacing a worn or damaged exhaust system restores performance, comfort, and efficiency while maintaining your Porsche’s distinctive exhaust tone.
Key Benefits:
- Restores proper exhaust flow and back pressure.
- Improves fuel efficiency and power output.
- Reduces noise and vibration.
- Ensures emissions compliance and MOT readiness.
- Built from corrosion-resistant stainless steel for longevity.
- Direct-fit compatibility for classic and modern Porsche models.
Upgrading to a high-quality standard exhaust preserves the car’s original performance characteristics while ensuring long-lasting reliability.
Highlights:
- Precision-engineered exhaust systems for Porsche vehicles.
- Optimised gas flow for power, torque, and efficiency.
- Durable stainless-steel construction for corrosion resistance.
- Designed for authentic tone and perfect fitment.
- Suitable for classic restoration and modern maintenance.
- Reliable, quiet, and performance-balanced solutions.
