I recenlty got a custom Magnaflow exhaust put in and the ower of the shop set me up with a 2.5in pipe from the cat-back. The truck runs great but now I'm wondering if 2.5in is too big. My wondering started after I read this post: http://www.ranger-forums.com/forum2/...ad.php?t=46663
Did I go too big for a SI\SO setup?
