in tryin to get my budget together for my 5.3 and/or 6.0 swap, im wondering what ya'll as running for exhaust setup? i would like to do it right the first time, from what i've gathered single 3" out the back will be plenty of pipe, so i plan to re-use my 3" in/out bullet its only about a year old. im mostly concerned with from the collectors to the bullet itself, everyone just running like 2.5" off the collectors into a y-pipe to cat to muffler? i would like to do it nice and have it mandrel bent the first time around, no makeshift setup to get it running and then upgrade later. just trying to get an idea of what i am looking at price wise.

thanks guys
