I know there are always posts like this, but I want to see a good one. What are the best mods that you have actually used that make good performance, considering their price? ex: k&n, airfoil, exaust, cat, tb, runners, headers, ignition box, etc. I would really like to know what you guys think from experience. Thanks for posting. -Brian

One of the major restrictions of the TPI is the air intake. Custom fab your own for that custom look and a decent performance gain.
