I wasnt trying to argue with anybody just pointing out that this is a subject with alot of different opinions as to what size of exhaust pipe to run, and i must not have read the title correctly i thought it was refering to exhaust pipe size not header tube diameter, thats my bad there. I dont want people to think i am arguing. I would rather have 2 1/4 inch exhaust pipe over the 2 inch exhaust pipe, i was just hoping the 2 inch would work ok because its brand new exhaust and i was hoping to avoid a 300 dollar exhaust pipe bill to get it changed.
