:agree:Put a diy intake on it instead, make the exhaust free flowing, get gauges, a valve body, and custom tune it. You can't stack anything
I made my Samsung SGH-I997 send this.
:agree:If you want that truck to last, stop modding it and start reading up on it before you continue.
K&N will kill the truck and you can't stack chips. Start with the basics, a intake that actually filters out dirt, exhaust, gauges and a chip from DP, TW, PHP, etc.
Read read read! So much information on this site it's crazy. K&N is garbage! you know mangaflow from gas engines? If you are doing a straight pipe, there are a lot of options, many cheaper then mangaflow.
