I got the Summit pre fab exhaust system they sell. They just need to weld it up. The TTI headers came with the 2" extensions/collectors. The header exits 3" but the extension it came with goes down to three. I think that is where he got confused. They do pretty good work otherwise. I guess he was cornfused. lol? I guess I should have Flanagan look at it after it's all said and done see if he can improve it a bit.
