Need 6.0l truck exhaust recommendation I bought a 06 silverado hd crewcab w/ an optional 6L engine and 4.10 gears to replace my 04 colorado wintercar. I can't find many catbacks for this application, so I think I may just replace the muffler. What mufflers give you a deep sound without annoying drone? I was thinking about flowmaster mufflers but I have no idea how the models sound- deltaflow, bigblock, 50 series, 50 series suv....

I have the FM 3" double-in/double-out muffler (P/N 530504) on my 01HD60. It's an X-style flowing muffler, effectively giving me an x-pipe for my custom duals. I got it installed in place of a home-made catback that used some very restrictive bargain "turbo" mufflers. The truck would not turn a tire in a straight line with the bargain mufflers, and now it does it quite easily. However there is significant drone in the cab, more so than I'd like. I have also covered nearly all of the exhaust piping with Thermo-tec exhaust insulation. That has removed about 10db of interior noise, but I need more db reduction. I'm looking to install shorty headers to see if that will get rid of the drone.
