its between offroad prochamber (brenspeed said they are hard to find? know where to order it and not be on back-order?) , or pypes offroad h or catted h? i want it louder but no "Trumpeting" and no rasp..... anybody runnin any of these set ups?

Prochamber, H and O/R H all go well with MACs. I have heard both o/r prochamber with MACs and O/R H with MACs. Both set-ups sound good. I am not sure if you will get trumpeting with an o/r midpipe. I am currently using my MAC axlebacks.

prochamber or catted h.

From what I've read around here you will get trumpeting with the H. Off-road or not. Even the high flows can do it. Resonators seem to take care of the issue.

Not sure about the prochamber. Not a lot of people seem to be running those.

yea brenspeed recommended the catted h ... but if i could find a prochamber id do that ... i want it quite a bit louder than just my axlebacks without sacrificing quality.

have you tried lethalperformance or stangmods?

FWIW i ran macs with my catted H..and it still trumpeted pretty bad and was somewhat raspy as well! id try to find a prochaamber and just put hi-flow cats on it if i were you.

Is there an o/r x for macs, or is it strickly h prochambers

Are you freaking kidding me? There is one and only one choice: offroad Prochamber. Find one, and use it.

i called lethal performance and they wont be getting any prochambers in... im calling stangmods in about fifteen minutes. Hopefully they have the prochamber otherwise i will have to go with the catted H.
