Help...questions on Exhaust System

Aight...a couple week ago my bro was backin up and hit somethin...i dont know what was it(wasnt with him)...well whatever he hit twisted the whole exhaust system...so we went to a shop(start with a m....cant spell) and they say they will put back on a stock system on it for 400...but the system that was on the car was aftermarket...so we said no...
the questions is what a good place to go to put on a aftermarket system for cheap?...or is it cheaper to buy aftermarket parts and have them put it on?

Thanks :iceslolan

Go to a shop that custom bends them, and get one done there..

yea...already did just wonderin cuz we want to replace the whole thing...kind of rusted out...

go to a different one cause those guys are trying to cheat you big time. go to another one and tell them you want what ever size pipeing redone from the catback. 2 1/4 inch is usually pretty good. i know aplace around where i live it would only be 80 bucks.
