Stainless steel, full valvetronic sports exhaust for the Porsche 911 991 Turbo & Turbo S, 2013-2015. This exhaust package includes performance manifolds (headers) which are equal length. The exhaust is a 100% genuine, IPE (Innotech Performance Exhaust), designed and produced in a specialised factory in Taiwan. The exhaust is hand-crafted from stainless steel and TIG welded to a perfect, direct fit. The sound is a high-pitched, aggressive racing sound that really gives the 991 the supercar sound it deserves. The tone is clear and smooth throughout all rev ranges
This 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.
