Engine/Transmission (1998.5 - 2002) Not Loud Enough

[Adam]

I've been running a straight pipe for two months now and I never really thought it was very loud. This was confirmed by the wife when she was in the truck the other day and said "I thought you took the muffler off?" Granted, the resonator is still in place, but it's just a straight-through expansion chamber, right? What do I have to do to make this thing sound like a Peterbuilt? I don't have time for a turbo-back system at the moment, I'm just looking for some immediate (cheap-quick) suggestions.



Thanks,

Hack out the resonator and deal with the drone or go 4" from the resonator back w/o a muffler or go to a full 4 or 5" straight pipe, Stacks work too.

6" Stacks might help.

If you want more noise loose the resonator and the turbo silencer ring and add an AFE Megga Cannon

If you want loud you'll get loud! (I love it)

Cut off the resonator, put a 3" to 4" adapter on your 3" pipe, get a 4" 90 deg and 4" 45 deg elbow, a section of 4" pipe, a hanger, some clamps and blow it out in front of the rear wheel. It will be loud I'm sure. Also as told, get rid of the silencer ring, and install a BHAF, K&N or AFE for real turbo whistle sounds. Shouldn't cost much either for the pipe. The filters can get pricy but open element filters really help flow the air.

I've had a little experience driving my truck with just the downpipe connected - this would qualify as loud - fast and inexpensive to boot
