07.5-10 LMM Duramax Powertrain
So, I bought a used 2008 3500HD 4x4 Crew Cab Dually. Living in PA, I am required to have a muffler. The exhaust was replaced at some point with nothing but straight pipe. I cannot for the life of me find an exhaust kit that goes from the downpipe back that includes a muffler. Does anyone...
