why is nobody running these headers??

I understand, and all dynos read different. They are both good products, and both seems to produce like numbers. It wouldn't surprise me in the least if some of the hype for momentum was due to the fact of left over inventory... Either way they both make power over stock, and the end result is .

I was not trying to cause strife, just pointing out that the momentums make close to the same gains if not equal to ppe. And lets face it. A tune does wonders for throttle response and the drive. But again we are talking peak HP (which honestly doesn't mean anything) torque should be the only thing people are concerned about as it is what makes your car "fast". Anyway, i have only ever seen a tune turn up an extra 3-8 peak WHP on our cars. We will have a better idea when i get my car on the dyno before and after tune.
