Porsche 987.2 "Sound Valve" Exhaust System
for Boxster & Cayman (2009-2012)
2.9L & 3.4 L
Our 987.2 "Sound Valve" muffler is designed to offer the best of both worlds, i.e. - stock-like sound (just a bit louder than OEM) when the valves are closed and a very aggressive, exotic race like sound when open... like we mentioned - it is truly "The Best of Both Worlds"! This system includes a key fob wireless remote and all vacuum lines, instuctions, etc. for a complete installation.
The enhanced note you will experience with the valves closed is very tasteful with an exotic car type sound - with the valves opened, it's a wild ride, developed for the enthusiast, so you can really enjoy the sound of your Boxster or Cayman motor!
In order to maximize performance and improve throttle response, both of these muffler systems are manufactured with a free-flow design in order to achieve our performance goals.
The SpeedTech 987.2 "Sound Valve" exhaust fits all 987.2 Boxster and Cayman automobiles (2.9L & 3.4).
For maximum performance gain and enhanced sound, we recommend installing our X-Pipe and tips with this muffler.
We offer a lifetime warranty of manufacturing defects for original owner.
