Conversation Between luiscarlos and Chris@Fabspeed

Luis, I'm sorry I didn't see this message till this morning. If you are still having problems with the catbypass pipes, give us a call. Did you reuse your stock gaskets or get new ones? We currently don't offer a gasket for the 2011+ Cayennes because people we able to reuse or buy a stock gasket without any problems.

Hello today I installed my secondary cat bypass in my 2011 Cayenne S and has problems.
After the installation I started the engine and the FS tubes had leaks were torqued hot and nothing the leak was there we had to make some round steel plates in the middle and use Wurth exhaust sealant.
Hmm not happy with quality...
