this has probably ask before but does any recommend a cat back exhaust that does not sound like a honda.
Pretty much all GM 4 cyl CB's need a good sized resonator added into them.
go to a muffler shop and ask them to make one for you. Make sure to put a good resonator on it so it'll baffle the sound down a little and if you dont want a loud bee hive sound... stay away from the like 6" tip fart cannon mufflers to use, lol
