hey guys, I did a search but didnt find the exact mods all together. I have an 05 titan with no mods, and I intend on trading for a 07 soon. I would like to do the following mods only : 2* advance, magnaflow 22" muffler only, and DIY airbox mod with airhogg/kn filter. What rwhp/torque gains could I expect all together??? Anyway to know? Best guess? Thanks for all your help.
