Call Farnbacher Lolles or call me and come down to Fabspeed. These is alot more ROOM under the end of a 987 than there is a 996TT car. As I have stated before there is resnonance in all 996TT exhausts systems including the stock system. On the Cayman 987 we engineered some special features that we are working on for the 996TT and 997TT to get everything with no negative downsides.


There is no resonnace in our 987 systems notice the 2 different muffler systems we have used.
