Paired this with MAC long tubes and Magnaflow axelbacks and this puppy really screams when I jump on it. Gotta love that idling rumble as well. It sounds great! Best sound on the street wherever I go,

Will this pass emissions/inspection Im pretty sure there is no way this will pass emissions or inspection, how much power will be lost if you used long tubes with a cat setup?

  • No, being an off road pipe it does not have catalytic converters. So if you live in a stat that does emmisions testing. You will fail. Also you will get a P0420 code as a cel if you dont have a tune.

    pro chamber quiet

    July 01, 2013

    The overall fit and finish are great. It tucked up against the underneath of the car excellent. The tone of the pro chamber is in my opinion very mild. You would swear it has high flow cats on it. I run off-road style. If you are expecting volume levels like a h pipe or x pipe this isn't the one for you. Like I said its a little quieter but it has a sweet sound between shifts at about 5 grand

    Best Sounding Mid-Pipe For the S197

    January 18, 2013

    I love my Prochamber. Hands down the best sounding mid-pipe for the 3 valve. After installing the Mac Long Tube headers, this is a breeze. Slides right on and gives you the adjustment with the legs to make it fit perfect for you. Stainless steel is just another plus going for this. The sound of a full Mac exhaust is amazing.

    Awesome sound

    August 15, 2013

    Almost sounds like the combination of an x-pipe and an h-pipe to me. I recommend this product.

    Deep tone!

    July 18, 2014

    The sound from the prochamber is amazing! Deep tone with no raspiness....almost sounds like an old 2v mustang. Paired with my mac longtube headers and borla stingers, you get a really aggressive sound, but smooth and not obnoxiously loud....that's what the electric cutouts are for!!!

    Great Product.

    December 22, 2012

    I bought this along with MAC long tube headers and ended up welding in magnaflow high-flow cats to the H-pipe to stay legal. A local shop installed the long tube headers, welded in the high-flow cats, and the MAC prochamber and had no issues installing any of the products. The exhaust was finished off with borla stingers axle backs. The car sounds great and it is a very agressive sounding car. It has a low rumble at idle, not too much louder than stock but certainly lower/deeper and meaner sounding. It also revs great and has a great muscle car sound during acceleration, which is certainly louder than stock. From what I have read, it would be louder without the magnaflow cats but that the sound would be more refined and not as crackly. I can't speak to what it sounds like without the magnaflows but I love the way it sounds the way it is set up. Would certainly recommend this product.

    Overall good product

    July 27, 2012

    I love the way this piece sounds, the pro chamber seems to give a much deeper and more aggressive sound then the rest of the mid pipe style's (i.e. x-pipe or h-pipe). Just like any aftermarket stuff it was a little bit of a hassle to install, nothing ever fits just right, but the install took roughly 3 hours including the axle back exhaust. Great product, would recommend to anyone

    The Pro-chamber is great...

    December 08, 2011

    I purchased the MAC long tube headers and off road prochamber, and also I bought the cat back Magna Pack Magno flow kits, now I have a great sounding GT, the parts all bolt on together great, would recommend this product for anyone. Shipping was great as well received the Prochamber in Two days. Everything was direct bolt replacement, no problems at all. I didn't install the parts but I was at the shop while it was being installed, and it took just about 4 to 5 hours to get the entire system put on.
