It will fit, however it may take some effort. The main reason most don't have it is there is no noticable gain. A 3 1/2" mandrel bent down pipe is all you really need, unless you just want 4"

MBRP is one of the best systems on the market and they say 4" is overkill. Yes there is a difference between mandrel bent pipes and the ones that aren't the sharp bends hinder flow in turn hindering HP gain and cooler EGT's and cooler EGT's are the name of the game.

Yes MBRP has done the dyno testing and they are one of our sponsors. Just click on the sponsors tap and there is a link to their website.
