i am looking to add power to the car i ordered the injen intakes from Lou and waiting to get them hopefully soon , i was also looking to get an exhaust system on the car after deciding i would rather keep the money for an exhaust then a set of wheels. just wanted to know when you change your stock exhaust does it change drastically the drive of the car or it just gives the car a small boost. sorry because i don't know much about exhaust systems. i read the review written by a gentleman here on the forums about the borla exhaust and liked them alot. i asked a mechanic he told me we can get them but i think they are illegal here in montreal for some reason unless he was wrong. which exhaust systems can you say help the car the most?

Thank you
