I have a 4in rough country long arm kit and when I was installing it I had to cut my stock exhaust to keep it away from moving parts on the lift. Will I have to cut this exhaust too?

In the question and answers, the question was asked if this will fit on the unlimited. MBRP Installer Series Cat-Back Exhaust (04-06 Wrangler TJ Unlimited).

    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.

    Sounds great, it's not to loud were it's annoying but it definitely makes your jeep sound like it has a v8 in it. I just got my first fill up in it and I am getting around 2 more mpg than I was getting!

    Cat back exhaust.

    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.

    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.

    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

    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.

    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.

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

    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

    I am a big fan of the MBRP system. Install was easy once the skid pane was removed. Has a great note to it, not too loud but has a excellent roar between 1,000 and 2,500 rpm. It has been installed for two months and still sounds great.

    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.

    I was hesitate to buy a brand I didn't know much about but after reading some review I went for it and did it pay off. The fit was great fits perfect with OEM cat and hangers. The sound is deep and is over powering at highway speeds. The black really looks great. I will and would recommend this product and any other MBRP product to anyone wanting a great sound, performance , or look out of there exhaust. Thank you MBRP for a quality, reliable at a reasonable price.
