Its a 1.5L motor. You wont get much sound out of it. Not really worth it IMO. I'd suggest to get a nice intake setup. I say this because according to other members, intakes on the crz seem to give the car a more throaty sound, while adding pretty decent gains w/o the ricy exhaust 'buzz buzz pop pop sound'. Ive yet to hear a good exhaust setup that I like for this car. Honda engineered the crz to have a nice stock exhaust note. And it sounds great for a stock 4 banger honda. I really like it.
