Kooks Stepped Headers

Does headers with double stepped primary tubes actually work? Can they really broaden your power curve more compared to standard headers? I was looking a potentially purchasing a set of Kooks 1 3/4" x 1 7/8" stepped headers with 3" collectors to pair with 3" Kooks catted X-pipe. This exhaust setup will be going on a Procharged Mach 1.

Re: Kooks Stepped Headers

Really depends on the combination. I run the ARH stepped headers on my combo with good results. Its 302 CI, High compression and see 8K+ rpm frequently
