exhaust systems DA9

[IZY-10]

just wondering guys what kind of exhaust systems are you guys running? and does it have the same configuration as the stock one?

2" or 2.25" exhaust with a resonator and good muffler(not a cannon!) should help your engine breathe a LOT. Check page 2 of the link in my signature for an idea of what it 'could' look like. The ED6 Civic and DA9 Integra are a very similiar exhaust setup
