Have you installed your own kit exhaust?

pretty sure exhaust are 304 and 409. 409 will take on a rusty apperance. i would prefer aluminized steel over that crap. yeah it will last, but looks like crap. a lot of oem exhausts are stainless and they get this oxidation that looks like rust, but they will last. oh and there is no need to tig an exhaust on a cruiser, maybe a blinged out trailer queen that the trophy whores will be crawling under. its going to do nothing for your performance, or longevity of your exhaust. stainless or aluminized. mig will work fine with the correct wire.
