I installed dynomax mufflers on my truck recently and was surprised at how quiet they are. The ones I got were 2.25" diameter pipe, 20" long oval case. I just switched to duals from a stock single exhaust setup and it actually is quieter now than it was. There was a noticeable difference in power as well, but that was going from single 2" pipe with crushed bends to 2.25" pipe with mandrel bends. Mine is a 350 with a four bbl though.
