actualy lol if you look on the video or the ast pic of the truck you can see on the ground was the exhaust i started building for one of my f-bodys its 3in with x pipe and i have two summit 3in turbo mufflers that goes with it. ill need to buy new hedman s pipes if i use it since my car had ball socket collectors instead of ones that use gaskets liike the truck has now. i just dunno if i wanna run the turbos or not though. :/ i will say the truck needs regeared though but it needed that before the new motor. it has 3.42s at a minumum of 3.73 but prefer 4.10 or 4.56's.
