1 3/4 or 1 7/8 headers?
has anyone tried the difference in primary tubes o a n/a 6.0 build? I figure the 1 7/8 may give me more peak but be down in the mid rpm compaired to the 1 3/4. just trying to get the right parts the first time ya know.

I have a choice between the 1 3/4 to 1 7/8 stepped header or just 1 7/8 primary header. 100 bucks difference in price. with a 4000 stall do yall think its worth running the stepped primary tubes? I know a stepped header will help down low, but with that stall would I be above the rpm range of where the stepped header is beneficial?

thanks for the info, id just like to know where the step header makes its power down low, if its below where my converter locks up then I don't see any gain in my application. but ive been wrong before.

That is everything to do with going from a restrictive 3" single pipe to a twin system, albeit probably overkill for the application and could have been better all round with a more appropriate system.

I bought the 1 3/4 to 1 7/8 step with a 3 inch collector. everywhere I read says the step design is better than a straight tube, plus can help in the lower rpm, and since its a street car I didn't want to leave anything out. id almost bet I cant tell any difference in this header and a 1 7/8 design but if theres a few extra ponies in them and I find a few extra elsewhere then they'll start adding up. looking for that 10.99 or quicker next spring!

I just give the larger headers the larger exhaust if it is 1 7/8 or above and the engine needs it. Seen some go from a real nice Y to duals and not pick up much compared to the 1 7/8. Never had a back to back 1 3/4-1 7/8 and Y to dual comparrison on the same vehicle though, just what I have seen first hand on different setups.
