Does anyone have a dyno comparison on Kooks 1 7/8 vs QTP 1 7/8 w/ HVM? I was wondering if spending the extra money for that HVM has produced results or is the same as kooks? I was hoping to see some results from very agressive heads and cam or big cube motors, like 408's plus.

 

thanks for posting this up, I'm wondering the same thing. Some people say they are the same header, but they can't be. One you can get with HVMC and the other you can't, and one you get get stepped and the other you can't. I have a set of SLP LT's to a X-pipe to 3" dual bullets. I'm leaning toward the QTP 1 & 7/8's HVMC race header but I would really like to see some dyno comparisions to prove it.
