[QUOTE="black4vcobra, post: 12787557, member: 82394"] Ya, I have the SHM 4.6/5.4 book and it does say that on a stock 03 Cobra that 1-3/4" makes noticably more power than 1-5/8". I'm sure tune and test conditions have a lot to do with the final power numbers but it's pretty clear that any LT header will be a major improvement than stock and there isn't that big of a difference between LT primary size [/QUOTE]
