why are you telling me to go round to local exhaust shops? did you not read my post, iam a mechanic in an exhaust shop. we do offer a lifetime warranty on some of our systems too by the way,
We weld up cracks in stainless exhausts from factory systems, constantly, cheap systems sometimes and also high end systems as well.
A big shiny stainless exhaust is a "wanky" item, they are marketed for the wankers who can boast about it down the pub, or on a forum in this case lol. even our suppliers tell us that.
stainless exhausts are good, but dont write off mild steel, both have their pros and cons
