So i just got a 02 sunfire with the 2200 and a 4 speed auto. i want to do this car right the first time so i got a few questions.i'm looking to do a header back exhaust, i want to put a resonator in it but not sure how to size it to the exhaust size as i've always had straight pipes on my other cars. i also want to upgrade the fuel system as i'm looking to put at least a 50 shot on it just for fun. if anyone can point me in the right direcetion that would be great. thanks
