By customer demand, our team at HHR is excited to announce our new SR2 dual-muffler Rear Exhaust for the 957 (2007-2010) Cayenne S, Turbo and Turbo S. Our all-new SR2 exhaust replaces the stock Cayenne rear muffler with two oval, straight-through mufflers for an increase in flow with less sound volume than our SuperSport and SR1 exhausts. Using our X-pipe crossover for a balanced sound, this makes the SR2 our quietest Cayenne exhaust while keeping the same straight-through flowpath as our SuperSport exhaust. The straight-through flowpath of the dual SR2 mufflers will provide HP/TQ gains with a milder yet deep exhaust note.
We hand manufacture this exhaust system in Denver, Colorado. The tubing, hangers and muffler bodies are made from 304 stainless steel. The low-profile dual oval mufflers tuck nicely under the car without protruding below stock muffler fitment. This exhaust utilizes your stock tips. Since the fitment of the 957's tips is more complex than that of the 955, we include 957-specific tip adapters for this generation of Cayenne, hence the additional cost over the cost of the 955 SR2. This exhaust allows fitment of your factory 957 tips, reusing the factory ball clamps.
We believe this is a DIY project for anyone capable of operating a wrench and a cut-off wheel or reciprocating saw, but fitment and trimming are needed to get your tips to align and stick-out correctly. Plan on approx. 2 hours for installation time.
The SR2 muffler inlets are sized depending on your model (S-V8 or Turbo), so please let us know what model you have when ordering. We build each muffler to suit your specific model, so plan on a handling time of 3-5 business days, after your payment clears, before yours is ready to ship.
