stock truck

[catman2]

You have a straight pipe which helps get the hot EGTs out but whether you get a chip or gauges later you should upgrade your intake now.

Pull the stock filter and the box and lid it was in and be sure to keep it all together. Go to NAPA and get a 6637 filter, a 4" long piece of 4" exhaust pipe and hose clamp. Stick one end of the 4" pipe in the filter, the other in the black intake hose and clamp them down. You now have a DIY Tymar intake for under $65.00. Your truck will breath much better, lower EGTs and gain some hp, at least mine did. Take the stock filter and box that you kept together and chunk it.
