06 si muffler what size piping?
I know some one selling a used 06 civic si muffler I was just curious if anyone know how they sound and whats the diameter of the piping on it? I would be bolting it up to a 2 1/4 exhaust with a test pipe, dc 4-1. I have a gsr muffler now that im using on that setup. i like the setup I just figured that si muffler a lil bit more flowing.
