      Video Review & Installation

      Ryan: This MBRP Installer Series Cat-Back Exhaust System will fit the 1997 to 1999 TJ, and this is gonna be for those of you that are looking to swap out your factory exhaust system because it's rusted out, bent, damaged or just because you want a different exhaust tone and a louder exhaust note from your Jeep. This is going to be a nice and easy one out of three wrench installation and we'll talk a little bit more about that in just a second.So an exhaust system for your TJ is going to be something that will change up the sound of your Jeep. It's not going to be something that is really going to add a ton of performance to your Jeep. Now, theoretically, anytime that you help the engine breathe either in or out a little bit easier, you are gonna get a little bit more power, but with the Jeep, it's going to be up at the top of the power band where you really don't spend a lot of time. So again, I wouldn't expect a huge increase in power from this item, however, you are going to get in much louder exhaust note and a lower exhaust note. So if that's what you're after, this is going to be a good choice. Now this system by MBRP is their Installer Series. This is an aluminized steel as opposed to a stainless steel, so it's going to be one of the less expensive options that are available as well. So if you're looking to get a system that will give you that lower and louder exhaust note on a budget, this going to be a great choice.So this is going to come with a muffler, your over-axle pipe, and your tip. The muffler, again, is going to be designed to fit on your Jeep without the need to modify any of the existing hangers. The existing pipe just slides right on. You'll have all the clamps that you need as well. The over-axle pipe will make the installation very easy, making this a two-piece system instead of a one-piece system. And you are going to get a 304 polished stainless tip. Now 304 is going to be a high grade of stainless. You're not going to have to worry about oxidation or rust on that tip, and the tip is really the only part that you're going to see of the exhaust system on your TJ anyway.Now, there are going to be shorter systems available. There are systems that are just a muffler and a dump. So if you're looking to eliminate the rest of this piping because you don't want to smash it on the trail because maybe your suspension setup makes it so that something is making contact with that tailpipe, you can go with one of those shorter systems. It's going to be even louder and a less refined sound. This system still having your tailpipe is going to give you a little bit of a more mellow, more refined sound, which is something that I personally like and it's going to be a very easy system to fit on your Jeep.This system from MBRP is going to come in at right around $215. That is gonna be less expensive than some of the systems out there that are stainless steel. Now if you live in the Rust Belt, you're looking for a system that's going to last as long as possible. You'll probably want to look at a 409 stainless or even a 304 stainless system, but expect to pay double or more what you have to pay for this system. This is going to be aluminized steel, so it's still going to have a good resistance to rust and corrosion, but nowhere near those stainless systems and that's why you can get it for a little bit less than some of those others.As I mentioned, one out of three wrenches for the install of this system. The only thing that makes installing an exhaust on your TJ a little bit more difficult is if you have rust on your factory system and chances are even the newest TJ is gonna have some rust. Exhaust systems love to rust.Man: Begin by removing the stock exhaust from behind the catalytic converter. Remove all rubber isolators and slide the exhaust out from underneath the vehicle. Install the muffler to the catalytic converter using the 2.25-inch clamp. Slide the muffler hanger into existing rubber isolator, slide a 2.5-inch clamp over the muffler outlet, then install the tailpipe to the muffler. Install the tailpipe hanger into the existing rubber isolator. Install and adjust the exhaust tip to suit. Tighten the lockbolt located on the exhaust tip. Align the exhaust as required. Starting at the front of the exhaust, tighten all clamps and connections. Your installation is now complete.Ryan: So if you're looking to swap out the exhaust system on your TJ for an affordable aluminized system that's gonna give you a nice low exhaust note and a louder exhaust note, this is gonna be an excellent option for you from MBRP and you can find it right here at

      Why Pick MBRP for Your Wrangler?

      Wrangler owners expect a lot from their ride. Yet many exhaust manufacturer's figure they can simply pack the same generic muffler into their Jeep kits that they put on a Civic. At MBRP we designed our Jeep JK/TJ muffler to match the very real demands off-roaders have for their rigs. After many dyno runs with various muffler designs, combined with real world testing, we were able to pull 9 RWHP and 15ft/lbs out of the 3.8L V6. The unique chambered design of the muffler provides a pleasingly rich rumble at idle that builds to a civilized growl at driving speeds and a throaty roar when you push the throttle down. Unlike fiber packed straight through mufflers our chambered design can handle getting wet.

      Here at MBRP, we put a lot of thought into the exhaust system. The muffler remains to the rear to avoid having to reposition the evaporation canister. We tucked the muffler up as high as possible in order to provide maximum clearance while keeping it in the factory location. The heavy 16 gauge steel construction is tough enough to stand up to anything that the road, or off road, can dish out. The mirror polished T304 stainless steel tip can be easily removed for off road adventures and replaced for driving around town.

      The Best Systems Start With the Best Materials

      Installer Series from MBRP brings you the best of both worlds. Designed and constructed to the exact same specifications as MBRP's Pro Series you can expect the same improvements in torque and horsepower and the same awesome sound as our top of the line products. The difference is the heavy duty aluminized steel construction. You save money without compromising on performance. MBRP Installer Series truly is superior to other aluminized exhaust products on the market. Heavy sixteen gauge steel is one reason. Another is that our systems have a thick protective coating of aluminum silica on the seams - an area that is often left exposed to rust. We are so certain of our Installer Series products that we back them with an industry leading 3 Year Warranty.

      Built to Perform

      You made an investment in your Jeep and would never consider less than the finest aftermarket parts for it. Your MBRP performance exhaust is designed to make sure that is what you get. Aside from a stylish classic look, you can count on your MBRP cat back system to give your Jeep a rich, mellow sound. And thanks to the fully mandrel bent pipes, MBRP performance muffler and minimal bend degree angle design you can count on squeezing every ounce of torque and horsepower your engine has to offer.

      The Premium Difference

      In an industry with its share of "commodity" exhaust products MBRP stands apart as a manufacturer of truly quality performance exhaust systems. You can see that in the way your system is packaged, the thought that goes into the design of every component, the consistent quality of the overall product and of course, the sound. The premium difference does not end there. Through our in house customer service team as well as the professionals who distribute and install our products you can count on your MBRP experience to be an enjoyable one.
