I'm actually running 3" Flowmaster Original 40s... they're loud and have a ton of drone in the cab. They sound cool, but suck on long trips. I'm actually in process of extending the exhaust toward the back of the bed. I have electric cut-outs and at idle, the mufflers are maybe 5 decibels quieter than the open pipe (guessing... I really can't tell much of a difference). I'm planning on using a quieter & smaller flowmaster Super HP2 with the cutouts closed and the 40s with the cutouts open.
