I am looking for a real muffler shop that can simply weld in a universal catalytic converter on my kids 1999 S10 Blazer with the 4.3l V6. The two local shops want $300.00 to bolt in a direct fit unit. I just want a universal welded in as this vehicle has 190,000 miles on it and I simply don't need the super duper wonder converter these guys are pushing. Does anyone know of a place in the Canton, Cartersville, Marietta area?
