I used Muffin Muffler I believe in the past. They did custom fab work for my center mount exhaust SLP loudmouth on my 2002 Camaro SS. Fantastic job. Measured out all the piping and bends to get everything to line up and be balanced and even.Anyone know of any competent exhaust shops in the Austin area? I want to do a resonator delete on my GT350, and it's really hard to trust anyone to touch it.
