What are you trying to gain? Sound or lettin her exhale better?
I cut my pipes about a foot after the cat, put a slight bend in it, and then welded up a straight pipe that dumps it before the rear tire. No muffler.
It sounds like a big block. A pissed big block. I feel it breathes a bit better, or maybe it just sounds louder.
The worst part of almost any truck's exhaust is how the pipes have to loop and clear the rear axle. Retarded. I'm no engineer, but I'm pretty sure having 4 right angles would restrict some flow.
