Just finnished installing the shorty headers and was somewhat surprised with the outcome.I removed the plugs for the install and reinstalled them when I was done. When I cranked it up it had a very noticable lope. It even rocks the truck back and forth. It doesnt sound like its missing, and there is a very noticable power increase. Is this posibly normal considering my mods? With all my mods should I run cooler plugs?
