Hello All,
'04 Silverado, 5.3, AT, 3.73's, 2wd reg cab long bed. Flowmaster cat back, redneck CAI (4" hose running from air dam to hole in bottom of factory airbox), AirRaid intake pipe, and a BlackBear scan tune. Since its light, the truck runs nice, pretty quick, but I'm wondering if shorty headers are worth it and what gains would I see? We always want more, eh?
Thanks, RT
