This item is a stainless steel, sports premium quality exhaust for the Porsche 911 991 GT3. The exhaust is a 100% genuine, IPE (Innotech Performance Exhaust), produced in a specialised factory in Taiwan. Top Gear are an official UK worldwide dealer for IPE and we are delighted to add their exhaust systems to our range. The exhaust is hand-crafted from stainless steel and TIG welded to a perfect, direct fit. The sound is a high-pitched, agressive racing sound.

Finally, the tips are a stunning, burnt tip finish pair that look fantastic on the car. 

The Porsche 991 GT3 takes the legendary 911 series to the next level. With its flat-six 3.8 liter, sky-high 9000 rpm engine and its tremendous handling, it is considered by many as one of the best supercars for the road and the track. At the same time, many criticize the sound of the stock exhaust system, as it fails to translate the real FEEL this German masterpiece of engineering should deliver for the ultimate driving experience. But there is no need to worry, because our full exhaust system is the solution you were looking for.

Our Valvetronic exhaust system for the Porsche 991 GT3 comes with headers and 200-cpsi sport catalysts in refined stainless T304 steel. The headers, sport catalysts, and the optimized valve-controlled muffler work together in total harmony to deliver a maximum increase in power and a breathtaking sound. Since this system is clearly equipped with racing genes, the sound is accordingly deep in the lower and middle rpm ranges, while being loud and aggressive at higher rpm. With our valve-controlled exhaust system your vehicle truly sounds like a GT Race Car. 

Power gain- +28.4HP at 7300RPM. Torque gain +31.3NM at 6300RPM. Weight saving 10,1KG from stock.

Innotech's valvetronic technology offers a sophisticated performance exhaust system that delivers both power and dynamic valve control to the driver's seat. The full system includes the remote capability to command 3 different modes: open, closed, and auto. In open mode, the valves are fully open for maximum flow and power, creating an exotic tone. When the valves are closed, volume is reduced for a more low-profile, comfortable drive. The auto mode enables the system to detect the engine RPM and fuel pedal signal to automatically adjust the valve movements. Furthermore, the muffler internals were individually designed and produced for each different car models in order to perform Valvetronic technology. Each product has its own unique sound and performance to break out of the ordinary.
