Product Description

Free domestic shipping to the Continental US!

HHR offers our ST1 straight-through, muffler-delete Rear Exhaust for the 955 (2003-2006) Cayenne. Our ST1 rear exhaust replaces the stock Porsche Cayenne rear muffler with an integrated x-pipe and straight tubes. Similar to our SuperSport exhaust, but without the resonators. This provides an even more free-flowing exhaust to provide HP/TQ gains, as well as provide a louder, more aggressive exhaust note from your Cayenne. This exhaust note provides a muscular, aggressive V8 sound under power, with more sound volume than our SuperSport.

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). This exhaust utilizes your stock tips. 

Our ST1 connects to your factory midpipe via sleeve/band clamps, just behind the differential. 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.
