Next TRD headers (pain to put on and a little expensive but worth it)
Have a custom 3inch exhaust done

What the hell is the Venom 400???
The KandN set is not really great for the Tacoma. You are better off cutting a hole in the stock airbox and putting a marine deckplate in the hole so you can cover it back up as needed. BTW you should probablely use the amsoil filter also. Don't even bother with any computer chips or anything like that.
