Steve worked on my 2012 Ram 5.7 Hemi, going from single exhaust to duals. I supplied a 3 inch resonator and Delta flow 50 Flowmaster and stainless tips. Steve did a perfect job installing my parts and installing 2 1/2 inch tailpipes. No rattles and no drone in the cab with this combination, just a deep rumble exhaust,couldn’t be happier. Would highly recommend Steve and Earl and Target Muffler.
