Installing a high flow catback exhaust is a quick way to pick up horsepower and torque. A catback exhaust will also give your Cayenne 955 S 4.5 V8/Turbo/Turbo S a sportier tone. All Milltek catback exhaust systems feature a bolt-on design and mate seamlessly with your factory or most aftermarket downpipes.
The resonated catback exhaust features a center resonator and rear muffler producing a more refined and quieter exhaust tone while the non-resonated systems incorporate only a rear muffler and provide a louder more aggressive tone compared to the resonated systems.
Milltek Sport exhausts are produced in high quality type-304 aircraft grade 2.75" stainless steel tubing. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore to ensure ultimate performance without the loss of mid-range torque.
*Note: Requires use of OE exhaust tips.
