Mac pro-chamber and mac 2.5???

Coupe5oh · 01-16-2002, 12:32 AM

what is the difference in the pro-ch, and the regular 2.5 offroad, it sounds better? if so, why? isnt it just a 2.5 system too?

I want better sound, plus my current h-pipe is vibrating on my crossmemeber and driving me nuts, so i will sell mine and get another, perhaps an x-pipe. thnx....

I have the Pro-Chamber Dumps. I think that is what you are talking about. Only difference is that the dumps are part of the muffler instead of being welded on. Mine is pretty loud. It is hooked to a MAC off-road H-pipe. No headers yet. At full throttle, everyone on the street is watching to see where the roar is coming from.

Bad89stang have you ever ran your car at the track? The only reason I ask is we almost have the same car.
