Shorter pipe = louder whistle

^that, and a 3" downpipe wouldn't hurt either

Some claim that removing the resonator will increase turbo noise, I didn't really notice a difference, but for the cost of a test plug, round 5 bucks, you can try that

Plug increases the turbo noise but not through the pipe. The only thing Ive heard that increases the noise significantly is a bigger charger

VVT or bigger Turbo!!!! FTW....... Lb7's mostly have the deeper grumble sound rather than screaming turbos of the newer trucks:thumb

your lb7 wont sound like that due to it not having the vvt turbo that the lly's and up have.
