Thanks for the input.
I heard KB uses a small diameter on the tubes but couldnt find the actual number. Anyone here know the tubing diameter on the Killer B or Full Race headers? Leaning towards these 2 at the moment. Ive read alot of guys have flange leaks with the Perrins so dont think I want to go that way.
Theres something that bugs me with each one though. KillerB, its the odd design. I dont like how all the tubes merge into 1 tight elbow. To me it looks like a bottleneck. Also all the testing ive seen show the 4 into 1 headers to move the powerband higher up (5k-7k+). Im not sure thats where I want it unless i was running higher cams, which i'm not. Also I have to use their uppipe, which isnt a huge deal, I just already have one thats working great.
With the Full Race, the powerband is in the lower range (3k-5k), which I would get more use out of. The problem is the thing is a tank and weighs more then the stocker and i've reduced alotttt of weight on the car so I cringe a little at the idea of adding weight back near the nose. It also looks like theirs might hang lower then others, but its hard to tell from the pics i've seen.
I ran across this dyno, which I thought was a good comparison of a 4 into 1 header vs the full race style. It shows where each places the powerband. Green being the full race header.
