My truck already had the 3 inch dp and no muffler when i got it. First thing I did to it was make it a straight pipe by cutting out the cat. Then guages and a tymar intake.
1st "mods" - normal maintenance type stuff, changed oil, changed fuel filter, changed trans fluid
2nd mod - did the Kwik 6637 air filter
3rd mod - did the Walker BTM muffler
The Kwik 6637 and the Walker BTM gave very noticeable improvements in acceleration and low end feel. The throttle is much more responsive and the truck just "moves" better.
I chose to stay on the mild side of the modifications. My truck is a secondary vehicle and its main job is to haul our 36' gooseneck enclosed car trailer. There are more expensive things to do, but these 2 simple and inexpensive things are a great way to get started.
Next up:
the Zoodad intake mod, a larger trans cooler and maybe a Superchips programmer.
Have fun,
BK Meyers
