    Which of the cat-back systems are street legal in California?

    PaulR

    • Since the MBRP Installer Series Cat-Back Exhaust system does not interfere with the catalytic converters it is not subjected to CARB regulations and would be street legal.

    How far approximately does the exhaust hang from the stock bumper? I have a very slim and small aftermarket rear bumper and I don't want the exhaust to hang too low or that would just weird.

      Review from MBRP Black Series Cat-Back Exhaust (00-06 Wrangler TJ)

      Perfect fit! Howeverrrrrrrrrrr. Caution on the install

      To take off the stock muffler and exhaust, you need to drop the skid plate that protects (AND SUPPORTS) the transmission. Once the skid plate is removed, the entire transmission drops 5-6 inches. Attaching the MBRP muffler and partial exhaust is impossible in this state as the hangar hook is out of reach. Discovered that you had to use a floor jack to lift the skid plate (and transmission) back into place to finish connecting the muffler. Once in place, perfect fit. However, was quite shocked to discover the "mis-alignment" - almost returned the product until messing with it. Would be good to caution future buyers who are installing this item at home in their garage.

      I was worried that this would be to loud and it would drown the tunes, not. It is a far better exhaust than the stock and I am seeing better gas mileage, acceleration and it sounds better. I could not stop there, I added a few more things to improve the gas mileage. I am glad I did it. Plus the black exhaust goes well with my black '04 Wrangler.

      MBRP Cat-Back Exhaust Review

      I would give it 3 1/2 stars. Good value for the money. Fits pretty well and sounds great. A little throaty, but you would expect that. Only issue was the tail pipe (rear) hanger was in the wrong place and orientation for my 2005 Wrangler Unlimited. I had to heat up the 1/2" welded mount and bend it 90 degrees to be in the right orientation, then I made a longer (doubled up) rubber hanger to make up for the location difference. I also added another hanger to stabilize the "side to side" action or it would bump into the transfer case when off roading.

      Review from MBRP Installer Series Cat-Back Exhaust (97-99 Wrangler TJ)

      Awesome exhaust!

      The exhaust was a great fit and the sound is much deeper and louder than stock. My install took a little longer than it should due to my old muffler needing to be cut completely off so I ended up welding the new one. But overall the sound and style is awesome especially for the price! Definitely recommend

      It took me a few hours to install mainly due to my rusty stock exhaust. After I got the stock exhaust the MBRP kit fit very well, you can tell it was made for Jeeps not just another universal muffler all the factory hangers fell into place and it curved perfect around the fuel tank.

      Easy install. It was easy due to two piece system. I have to use a cut off wheel to Cut the old one off. It was louder than I expected but it's not a dronner or to loud. Over all pleased.

      Nice bark for the price

      My install was a little different since the previous owner of my TJ had a universal cat welded into the system so it took me longer to install. If your TJ is stock I could see this getting done in about an hour. All of the tubing bends are in the right spots with a good amount of axle clearance over the rear end. The sound is nice a mellow tone, not too loud but noticeable over stock.

      have had it on my jeep for about 2 weeks now no problem love the race not it hits when you get high rpms at low rpms its got a pretty deep note my buddy has the flowmaster cat and there notes are almost simmilar at low, it took me about two hours to get everything on all i did was jack it up and disconnect old one and cut it in half to save time trying to get stock out of there other wise you will waste time and putting in new one wasnt that long had to do some adjustments but in the end love the look the slight tilt out behind rear passenger wheel looks mean and gets attention already!!

      Exactly what I wanted.

      Cat back took about two hours to install. The only issues I had was taking the old one out because of some rusty parts. But that's jeeps for you. Once the old one was out the new one fit right in bolted it up and in no time the new exhaust was in. This exhaust produce a nice low rumble sound. Nothing super loud but loud enough to know. I have a soft top on my jeep and I'm still able to have a conversation in my jeep at highway speeds.

      1 Hour install

      Easy install. It took me longer to read all the reviews than to install the cat back system. After getting my jeep on jack stands I supported the transmission with a screw jack. I lowered the cross member on the passenger side by leaving the center bolt in but loosened on the drivers side. This gave me good access to the exhaust bolts behind the converter. I sprayed penetrating oil on the exhaust bolts and hangers. Sawed the old exhaust off behind the muffler. Out with the old and in with the new. Great Sound at idle sounds like a v8 and not over powering on the highway. Thanks
