looking to get a little more outta the truck i am not messing with the ip just wanna upgrade exhaust and air intake

as for exhaust it has 2 inch true duals with glass packs and 5 inch tips, is this pipe to small?
the truck runs great and i am getting 15 to 17 mpg so it seems to not be affecting performance. whats your opinions

has stock air cleaner minus tube from cleaner to grill
should i make a cold air still out of tubing or not bother


to add i can fabricate so anything that you guys may have seen or done can you please let me know or point me in the right direction

 

Turbo it, the other mods won't gain you much

 

I cut the air cleaner so now it looks like an old carb motor alot better throttle response i can post a pic when I get home from work and it is a lot loader also
