Okay so I finally got my heat exchanger from ottperformance.com.. it didn't come with directions so i have no idea what i am doing. When you guys say "the big one" how do i know if mine is the big one??? There is two sizes?? I honestly do not feel like taking my bumper off unless i really have to. Is there a way to do i without taking the bumper off? Is there any fabrication involved, and does the stock h/e need to come out as well? Please HELP!!

 

OK since you actually listened ima try n help you out. As far as the size difference i don't think it matters but you might have to modify something. or do a little research on the product. hope this stuff helps.
