Here's a quick video.....sounds really deep and loud going down the road. YouTube - Lifted F250 7.3 Diesel 6" Stacks
I vote take em off, but either way the truck will look fine. If you take em off you got any plans to patch the holes left in the bed?
Stacks are BADASS they sound great, look good, and look even better on your truck. everybody has side exit exhaust, I've only seen 4 trucks with stacks and 3 of em were dodges and 1 was a tiny ass chevy 1500 gasser with 7" stacks... I know FAIL
