I am trying to find a Mac Pro Chamber for my 2001 Cobra. I need to keep my cats though, the only two version I can find are Off Road and LT's. Can anyone point me in the right direction?

i just checked Mac's website for ya.... they dont even list it as a part, i dont think it exists man......

just go Bassani catted

or you can get yourself some hi-flows and have them modded into the Mac.... doubt its worth all that.

Mac discontinued the Catted Prochamber awhile ago. They only offer the regular o/r 1 and the o/r for LT's. Your best bet is to try and find one ebay. A catted prochamber will be so quiet it will sound like your stock H. Get a High Flow Catted X or a MRT High Flow Catted H.

Thanks for the replies guys. Who is MRT?

I have read online that the X pipe has a really bad resonance on the freeway, is that true? I checked out the MRT catted H pipe and it is pretty expensive...

Sorry for the double post. I have done a lot of reading about this, what about the BBK Extractor series X chamber mid pipe? Seems similar to the design of a Prochamber, kind of a hybrid between an X and a H...

Thanks for the help guys!

I'm not a fan of BBK, IMO they make crap products and sh*tty quality, that's why its so cheap. If you want a x-pipe go with a tru x-pipe such as: Magnaflow, Dr Gas or UPR. I believe American muscle sells the catted Magnaflow x-pipe with Free Shipping plus you can get the forum discount if you have 50 post. MRT and Magaflow will both be expensive but both are Stainless Steel (so they will never rust) and the fitment of both is A+
