hi,i have a 67 f100 with a 429 cj with dove-c heads 750 edelbrock carb and performer intake (400 hp??????) Going to put l+l headers on,would i be better of with 2.5 or 3 inch pipe all the way back.cherry bombs or flowmasters?I have flowmasters on it now 2.5 in/out with manifolds.Always liked the sound of cherry bombs(bumble bees)

 

Go 3 all the way more flow an sounds better. Now with the muffler i love the sound of a 40. I am running a 3 inch all the way with headers an a 40 an it sounds good.
