    spt exhaust

    hey all i have a 11 wry, I got it used and it came with the spt exhaust, im trying to find online the diameter of it but im having problems does anyone know fro sure the specs on it? I wanted to go full turbo back soon but now im thinking i may benefit from starting from scratch and getting a whole new exhaust system. does anyone have a after market DP that works with the spy cat back?

    You can fit a Cobb DP on it. At least you could with the '08 hatchback SPT.

    Cobb, or any other with an adaptor, they are around $20-30. The spt is a 3" exhaust, that tapers to 2.5" at the mid pipe and at the entrance of the muffler, I think.
