Im gonna look more into gdawgs suggestions, solo or borla. I shelled out 325 already, cant see adding another pipe for 175. Now im close to a cat back system. I gotta do some more homework on the solos, did a quick search not long ago and came up with a bunch of posts from here and the Z forum. Pretty sure i read there quality wasnt all that great a few years back. Hopefully that changed, do the have a lifetime warranty on there products? I think nick sells the clamp in mach 40 for $362. Surprised the Carven is cheaper just appears to have a superior quality imo
