Took it back to shop and they welded it back together and took out the flange that fastens the front half to the cats back. Now I get off of the highway tonight and it cracked right where it comes out of passenger side manifold. Is there a reason for this and what kind of alternatives do I have. The shop says that there is not much he can do with it except for keep welding it-- (does not sound like an permanent fix!!) The front half of this darn exhaust costed me 315.00 and to have it installed was another 165.00, and I was wondering if this is common among Gmc and chevy-- (that is what the exhaust shop tells me. Thank you for any suggestions--
