HHR offers the SuperSport Rear Exhaust for the 955 (2003-2006) Cayenne. The SuperSport rear exhaust replaces the stock Porsche Cayenne rear muffler with a pair of polished resonators with an integrated x-pipe. This exhaust provides a free flowing exhaust to provide HP/TQ gains, as well as provide a deeper, louder exhaust note from your Cayenne that is very livable on a daily basis. This exhaust note provides a muscular, aggressive V8 sound under power, with a pleasant rumble under normal driving conditions.
We hand manufacture this exhaust system in Denver, Colorado. The tubing and hangers are made from 304 stainless steel with a raw/mill finish. We integrated an X-Pipe into the 2.5” or 3" stainless exhaust tubing for slightly better flow and to improve sound characteristics (we initially tested this setup without the x-pipe and prefer the sound properties with the integrated x-pipe). The resonators are highly polished stainless steel. We utilize low profile mufflers that tuck nicely under the car without protruding below stock muffler fitment. This exhaust utilizes your stock tips.
We believe this is a DIY project for anyone capable of operating a wrench and a cut-off wheel or reciprocating saw. We provide detailed instructions and needed hardware. Installation time is estimated at 120 minutes. Please note there is a 5 business day lead time to ship this exhaust since they are hand-built for each customer.
