I'm Awesome
from the headers back should I include the glass packs I already have on the truck OR just get rid of them and run no cats and no mufflers for a nice tone or is the glass pack a better way to go I'm confused as to why my uncle with a 95 5.7 tbi (who has his exhaust ending right under the seat due to rust) has a quieter truck then mine but a kid at school has a louder truck with mufflers and straight pipe and no headers on a tbi
