Exact fit, on time delivery and the price was right.

1993 GMC C1500 Muffler

Very Satisfied
Reviewer: walker muffler

I replaced the entire exhaust system on a 1995 GMC Safari SLE for under $100.00. The estimate I received from Midas was in excess of $600.00. The parts were all Walker. Definetely a "no-brainer!"
