I just had duals with no mufflers installed at a local muffler shop. The guy at the shop is a "craftsman" at custom exhaust and he did excellent work. The tapered chrome tips sticking out the back look good and the exhaust tone is deep and mellow at idle. Under acceleration, it raps with authority as I shift the 5 speed tranny. He used 3" pipe w/3.5" tips.
