3" Exhaust
Just bought a MY05 Sti which is stunning, its kicking out 380bhp and currently running a full 3" exhaust which is quite loud to say the least, can anyone recommend a good back box or sports cat that will quieten things down a bit and would I need to have a remap done after fitting either of these?
Cheers
