2005 Porsche Cayenne Turbo with Fabspeed Cat Bypass pipes and custom muffler exhaust bypass. Installed 1 3/4″ pipe that connected to original exhaust piping in front of the muffler, routed around the back and side of the muffler and into the back end of the exhaust tips on both sides. Kept the stock exhaust look but gave the truck a much louder and sporty note. It sound louder in the video than it actually is. It does have some sound too it but it isn’t annoying or over the top.
