Pretty sure this is the right area to post this question. Regarding future ls swap in my truck. I've searched all over this site and web. Has anyone owned or been underneath one of the 4.8 Silverado or Sierra RST 5 speed to know what the exhaust set up is? I know they run shorty style headers by JBA but from there back I have no clue. Really enjoyed sound of one I heard in person. Anyone know their configuration, pipe size, muffler style? This would be going on an LS powerplant in a standard 92C1500 RCSB.
