I am changing setup to a h22a ing my 92 4dr civic and want to know the best exhaust to put on with this set up. I recently asked this same question but for the SIR 2 . I will be looking for a deep sounding exhaust and no prefence as far as price goes. NOT rich just want to know the best for this setup. oh yeah i was looking into the apex ws 2 but they don't list it for the 4dr....? does anybody else list for the 4dr or any good ideas...?
