custom aluminum 3" catback exhaust? Good? Bad? OPINIONS
oK so i have like 25 feet of aluminum 3" piping. I have a bender that bends three inch pipe. Now, what i want to know is if that would be okay using that **** instead of steel? I only want to cut off at the end of the cat, and fabricat my own 3" cat back? so it wouldnt really matter if i used it right? it is metal i know its not really tough and all but as long as i aint hitting like massive speed bumps and **** it i should be fine right? I dont have money to buy steel pipe i am just wondering if the aluminum would be alright for the time being?

do any manufactures use allum? if not then dont do it. also 3" is a little big. unless your adding 100 hp, port and polishing your heads then 2.5 is probably as big as you should go least you ruin all your exhaust velocity
