So you have the SPT or the Borla? Guess by your description it must be the Borla?

The Borla is a 3" single, into 2.5" dual, into 2" quad, their tips are 4.5", that is pretty huge. I want to try and find the same specs for the other exhausts. I do believe the SPT is 2.5" all the way, so the single is 2.5" versus the 3" on the Borla. Invidia just says they are 3", so I guess the pipe is 3" all the way through.

Anyone know the specs on the Perrin? Edit - Just checked, they are 3" straight through to 3.5" tips. Tiny compaired to the Borla

MaSTi - Why would you not touch Borla? Does the brand have a problem? ie rust or something?
Borla OEMs the SPT exhaust for Subaru. I have the SPT exhaust on my '11. It isn't 2.5 all the way.
