O/R Prochamber vs Catted Prochamber

auburntiger7231 · September 18th, 2007, 12:02 AM

I have an O/R Prochamber on my car right now and I love the sound. What I don't like is the smell!!! It's horrible! It's rattling a good bit so I guess I need to get under there and tighten it and maybe that would help. If not i'm gonna get rid of it and get one with the high-flow cats.

My question is this; What difference would there be, if any, in sound/volume and HP if I went with the Prochamber with the cats? I love the way my car sounds with the Mac and Flow 40s(although a bit louder would be nice) and I don't want to compromise that if possible. TIA

Wouldnt be any lose of horse power since it high flow cats not much if anyway. The sound should change much either.There really shouldnt be much of a difference at all.

You car will be noticeably quieter with the cats. The sound might seem a bit deeper in tone, but definitely quieter. You'll only lose like 1-2 HP at the most. Not a real big change in performance. You probably won't even feel it. I know they make catted legs for the prochamber, but good luck finding them.

O/R pipes are a little louder, but the performance won't really change at all.
