This is going on a 89 crx si..stock midpipe...has new/factory resonator...im getting a 18" body (24") magnaflo muffler....Its probably gonnabe crush bent piping . Ok Is 2" gonna flow ok on a dohc zc??Currently i currentlyhave the d16a6 with freeflowing cat and intake...I need to also know if 2 1/4 is gonna be louder? I want my car quiet but with decent exhaust flow..Will it sound higher pitched with the 2'' or 2 1/4..Any response soon would help since i will be buying a muffler tonight
