Default Borla XR-1 Racing Mufflers..

I want to purchase one for my 951. Stock exhaust with a Bursch testpipe.
What is the EXACT model I should pick up? How much power should I pick up with one? http://borla.com/products/xr-1_racing_exhaust.aspx

Thank you

I don't know anything but the power part. There is someone here that has cut the stock muffler in two and determined that the stock piece is very straight through so don't expect much gain. All the gain from going from a stock exhaust to an aftermarket one is the deletion of the cat. Good luck.

I don't see how that can fit on a turbo... Isn't that basically a collector?

Ok. I'm not a turbo owner (the one in the sig is Dad's) so I dunno exactly how the exhaust is routed...

Wouldn't the 3" inlet one fit stock exhaust (2.5") since it would be clamped down??
