01 Rappin Chevy 3500 D/A

[Butch]

Got the stack pipe on about 2 weeks ago but think were gonna have to put a resonator or a muffler on it.Man,when ya punch it it sure raps taking off or kicking it into high gear.We even isolated the exhaust from the cab with rubber grommets but the rap you get off from it is unbeilevable.And when ya use the tow haul its worse yet.Nothing but pure power sound coming off the stack & you can hear the turbo whisle as well.Sounds like a big rig & not a small pickup.I hate to see what it sounds like pulling my 19,600 trailer,that'll make it bark.Sounds like a machine gun,LOL.

They sure are loud arent they. Do you find yourself driving in T/H alot with the rear window open?? I do.
