Started with 96 the first year and did not hook up. Went to 144 up the middle with 1.375 in length. Hooks up very well! 1 pic for every HP

I have an 06 and have always run 192 but turbo'd up, 144 should be fine for stock. I run 1.325 and have torn out 3 sets of pipes but sounds like guys are running longer. Had a fab shop design a metal plate to cover the pipes now seems to be working OK.
