I'm on the verge of buying an exhaust system for my 2006 Cayman S. I think I have narrowed it down to Fabspeed (have on my 2001 911),
Billy Boat, or APE. By the audio clips I've heard, the APE's sound is most to my liking, the APE's price appears to be the lowest, and power gains seem comparable for all three. I haven't compared weights. By the photos, Fabspeed and
Billy Boat appear to be of higher quality and robustness. Thoughts, comments?
Also, I noticed that Fabspeed,
Billy Boat, and some others have cross pipes between the mufflers and their muffler exhaust pipes run directly to separate exhaust tips. APE lacks the cross pipe and muffler exhaust pipes merge into a single element (Dream 1) that feeds a single tip with two outlets. What are the implications and effects of the different designs?
I'd appreciate any advice or guidance. Thanks.
