Flowies all the way buddie, I get comments from idiots all the time, "is that a v8
"
I have a 22re, 40 series, 2-1/4" header back, never installed a header yeat, but i imagine the one i buy the outlet will match the 2-1/4" tubing....i ended up paying 320, installed, bent, tucked, complete w/ new 40 series, gaskets, & cat removal.(lack of welder & bender, i had to pay, if i could do it, i would)
a 3.slo might do well with 2.5" but i have no experience w/ them so i cannot say, seems that it might do, the main thing is that you do not want to loose backpressure, very vital in proper exhaust setup.
I am very satisfied with mine (40 series) it is agressive, like others have said, it is loud sometimes, with proper shifting and crusing speeds, that thing sounds sooooooooooooooooooo sweet. Flowmaster=American Thunder
Oh, and if the tip points slightly to the ground, it bounces back, and almost "amplifys" the sound.
