Hey everyone... im looking for an exhaust muffler or system that sounds mean but will not explode my brain while driving down the freeway.... I have not heard any CTT with exhaust on them but i was messing with mine tonight an found out that with the clamps loosend up behind the secondary cats it sounded good driving in my neighborhood.... I would like to get that muffler system that has the built in by-passes but for $2k i can buy cutouts and weld them in myself....hahaha.....Also has anyone done the secondary cat delete pipes on a CTT??? is there a diff in exhaust sound by much??

Thanks

 

Go for a quality piece I can recommend Fabspeed, but I like the Tubi specially on the ctt.

 

2nd on the Tubi's, they really sound great!!

 

Carldh--We offer secondary catbypass pipes for the Cayenne Twin Turbo vehicle which not only save weight but increase overall HP/TQ. The secondary catalytic converters on the Cayenne's are not needed to pass emissions and inspection and are placed by the factory to limit the aggressive tone of the 4.5L V8. Our dual Maxflo mufflers are constructed from T304SS and save considerable amount of weight as compared to the stock muffler. Here is a dyno graph and a soundclip of our Cayenne Twin Turbo S with the catbypass pipes and EVO air intakes with diverter valves. Mufflers will be installed early next week. If you would like more info email Joey@fabspeed.com or P.M.

I used them for my BMW 645 BMW M5, CL500.

He is doing the 2009 Turbo S for $1K installed. It sounds great and so cheap. They do all the exhaust in house shop.

The M5 was $1400 installed and sounds like a Ferrari. Have a F430 with Capristo test pipes and race muffler I can say it is 80% close to that.

I have no idea why people charge so much for a pipe for that by pass. Even being stainless steel it is pretty cheap.

Check out the site and pics. All high end stuff. He does the Bentley also. Sounds crazy and still cheap.

I have FabSpeed cat bypass pipes and mufflers on an '09 Turbo S and love them. Compared to the cost of the MTM exhaust I put on an Audi S8, the FabSpeed system was a steal!
