Re: 1991 V3500 Project Heavy Hauler
Thanks for the compliments guys.
Hope you find your leak Larry. A flowmaster sound with no drone or interior resonance sounds like a great product. I took the wife for a ride last night and she approves of the volume. I haven't driven any long distances so haven't picked out any specific annoying rpm bands. It does have a little of a high pitch type purrr at light load but honestly I can barely hear anything with the windows up and exhaust exiting about 15 feet behind me. One possible difference besides the single vs dual is I'm running a magnaflow cat too. Exhaust is still a little stinky and it set a rich left and right bank fault code yesterday. I'm using GM LS1 injectors from a 98-00 motor and they flows little more than stock.
