If memory serves me rite the pipe is 3.5
It's a bit tite with the column shift linkage but it fits.

It dumps just below the drivers seat or should I say bench LOL

No muffler needed, its very quiet until you get after it then its just turbo whistle

I don't plan on a pipe on the wastegate yet
If the car was really nice then I prolly would

I like racing it cause it looks scabby, its always fun pounding a fox body or camaro up there assess after they just wiped on a fresh coat of race glaze LOL
