Porsche Cayenne S 4.5 V8
Just fitted a Milltek resonated exhaust on my '08 R8! Man...what a sound...should have done this ages ago. It's not too loud, just a little louder, and enough that I'm driving everywhere with the window cracked open!
Milltek Sport have developed a performance exhaust system for the Porsche Cayenne S 4.5 V8. The system is available with optional catalyst replacement pipes (cat bypass pipes) which remove the lower catalysts. These catalysts are not regulated by lambda sensors so can be removed without causing engine faults and the car still retains the primary catalysts.

The rest of the system consists of silenced or unsilenced (resonated or non-resonated) front sections, connecting pipes, rear sections and a heat shield. It uses the tailpipes from the standard OEM exhaust system. With it's high-quality construction from type 304 aircraft grade stainless steel comes a dramatic weight saving over the standard system. The full Milltek system with unsilenced front pipes is a, not insignificant, 20kg lighter!

As with all Milltek Sport exhaust systems, performance increase and improved driveability go without saying, but the change in the exhaust note is incredible. Watch the video clips (see 'Associated Media Files' below) and make sure you turn up the volume - it's well worth it!!!
