My fav part is the 5 inch tip I thought it would look kinda ****ty but it turned out looking bad ass and added a little roar sound to the exhaust. O and on my way home I would be doin 60mph then layed on the gas it would kick in with high rpms then jerk and run low rpms. But it still drives fine normally I'll check the tranny fluid tomorrow well today. AND GUESS WHAT my mpg went up a bit i think I didnt use much gas (i filled up b4 i came home an hour ago and I was doin 90 on the way home and I filled the tank up to the neck and ended up with a hair under a full tank) I think takin the tool box off helped mpg. I do have all the tools in my back seat (i got room for 1 person still but never use my back seat) and Big'un can u ps some heads on my truck if i find the style i want?
