Does anyone know what kind of power gains the MAC prochamber H can deliver? I know X's are good for 10-15 hp, but I was wondering if it was the same with an offroad prochamber. Thinking of goin with the prochamber midpipe with either magnapaks or jba's muffler
Typical rule of thumb is that X's give a tad more top end HP with the same tad bit lost in low end torque, and visa versa for an H pipe. The Prochamber is something like a "wide open" X on the inside, only with H style sides...kinda hard to explain but its sort of like the two combined. I've read that on a 5.0 the gains are maybe a couple hp more than the other two, but you won't notice them anyways so pick what you'll like the sound of.
