I just got a 1994 Toyota Pickup. Its pretty much stock performance wise. It has a 4" Skyjacker lift and 33" BFGs. As far as i know from all my other vehicals theres always some type of free mods to do to your engine to give u alittle more hp. I was just curious if the 22RE has the same thing. Also, im putting in a flowmaster 40 series 3" single inlet - 2.5" dual outlet, this should be ok right?
