hello guys, I just created this account after lurking around for a while. Now, here's my problem.. I just put my truck in the shop for a bumper paint job and I noticed my muffler was hanging dangerously low, they clamped it twice as a temp fix until I got a weld job, both times it held less than a day. To make a long story short, I need a new tail pipe and muffler and my body shop guy is telling me he can't find any aftermarket for an 07' QX56... and that the OEM are $500.00 each for $1k total...that can't be possible can it? any and all help would be greatly appreciated.... I'm looking for a nice sounding quality exhaust if possible.
