sometimes you dont only buy a exhaust system thats cheep. as any of you know, different exhausts sound different. some have rasp, some drone, ect. some ppl dont like some of these sounds. in Bens case, his exhaust has alot of rasp, which he doesnt like. also, some ppl like certain exhaust tips. i like my borla tips, just because i can. lol. anyways. the borla is stainless, which if you didnt know, will not rust. so, buying an exhaust system for some ppl has different meanings. lol, not eveyone has a 900hp car too.
