Installed very easily. Immediately gained power that helped my 1999 Jeep Cherokee tremendously. Only concern is the clearance with the rear passenger side shock body. Might be an issue at full compression, but might not be. Sound is not too overpowering by any means. Would highly recommend this to anyone in the market for a solid exhaust system at a very good price. Also, most components are Made in the USA, so big win!

I do like this exhaust system. The bends were true to the OEM pipe and it was a cinch to install. Only negative is that the stainless steel tip (or is it chrome? Not sure) is showing signs of oxidation only 24 hours after installing it. Sure, it did rain all day yesterday when I broke her in, but I wouldn't expect rust so soon. Thinking either I'll dremel grind it off on the very tip of the tip or simply break out the reciprocating saw and put an aftermarket tip on there. Either way, this went on a blacked out Jeep and this is the ONLY non black part visible. Still, it does the job adequately and sounds fantastic paired with my Magnaflow High Flow Cat that I installed at the same time. I would call the sound this makes a medium growl at idle. You will feel much more acceleration and hear more of the glorious Jeep 4.0 motor in the 2K-3K RPM range. At least, that's my experience. YMMV. I would probably buy this again if I needed to, but I live in Florida and this vehicle has never seen snow or the salt associated with northern winters so I doubt it will be necessary. 1998 Jeep XJ, RWD. Perfect fit.

Fits perfectly. Suprisingly, I was able to cut the clamps off the old muffler and slide it off. Slid this muffler on and the attached the tailpipe, attached to the hangers and tightened everything up. NOTE: When I purchased this, description noted you needed to purchase an additional hanger. I did not need this, that hanger was included in the kit, so I returned the extra one I bought separately. FYI. As far as performance/sound, it is quite a bit louder than stock. I did buy this to replace a rusted out system that had a hole just aft of the muffler. So how much louder is hard for me to say because I drove my XJ for two months with it really loud so this was much quieter than that. If want something similar to stock this could be a little too loud for you. Check out some of the videos on youtube of XJs with this setup. I really like the tone at idle, nice sound for an inline 6. Again because I had a hole in the tailpipe, the metal had bent and was restricting exhaust flow. So I gained a considerable amount of throttle response with this, but I was very much below stock performance levels to begin with. Again how much better than stock, hard to say exactly but I think even replace a stock system you will see performance gains. I definitely think it is worth this price over stock exhaust components and should last as long as anything not stainless steel. My system did have a slight burning smell for about the first 6-8 weeks after installation. Mostly the oils and coatings used it manufacturing burning off. It also doesn't help that there is a sticker on the tailpipe near the tip that I didn't remove and it kind of smoldered a little when the exhaust was hot, oh well. Might want to remove that first...

After 15 years the muffler on my 2000 Jeep Cherokee Limited finally gave up the ghost. I replaced it with this cat-back system, and I'm pretty pleased so far. I already had the vehicle ready when the box arrived, and Installation took all of fifteen minutes. The parts were packed well and everything arrived without damage. It got here pretty quick, too, even though I selected the free shipping option. Although the product image only shows two clamps it came with three - which is exactly what I needed for the job. The inlet on my old muffler snapped off right at the muffler so I still had the full length pipe from the cat, and the muffler fit it perfectly. The hanger on the front part of the tail pipe was in the correct location, and the included clamp for the rear hanger made it an easy install. I was a little worried that the straight tail piece might have issues with the trailer hitch, but it's angled slightly and it fit perfectly. As far as the sound... I think it's a bit louder than the stock muffler, and it's definitely got a rumble to it... which I kind of like. I've been running it for about a week without a muffler, and it's definitely a LOT more quiet than that! Being as old as it is, I didn't want to spend an arm and a leg on a cat-back system. This one was very reasonably priced, and it seems to do what it's supposed to do. I have no idea how long it will last, but for now I'm very pleased with it.

I purchased this kit to replace the stock exhaust on my 1998 XJ. Amazon had the best price I could find so I went ahead and ordered it along with a Magnaflow Cat. Shipping was amazing, had it at my door in two days. Installation was more or less painless. The hardest part was taking the old exhaust system off. For this I would suggest using a recip-saw or an angle grinder with a cutoff wheel. In this case I used a recip-saw. Mounting it was easy, just a matter of attaching the clamps and tightening them down. If you have one, I would suggest using an impact driver to do this. It would cut the time needed to install this considerably. The exhaust sounds great at idle and really opens up when you give it some gas. All in all a great product, we'll see how well it holds up to the Ohio winters though. I'll update if anything changes. *Bottom Line* Awesome kit, easy install, use a recip saw and impact driver if you have one.

Internals rattle so bad and tried to use the limited lifetime warranty due to a poor weld. I was only offered a refund and not only has this went up in cost but it will cost me more than replacing the muffler that failed. Had this been a warranty then I would have no issues but apparently warranty is not for Amazon customers. Won't be buying another. Buy it if you like metal on metal noises coming from your exhaust.

'Cat Back' but not including pipe from catalytic converter to muffler, but for many it will be time for a new converter also. Ordered this from Amazon directly, and it arrived via UPS in good shape in a full box.. I really thought it would come just wired together and a bit beat up as I've seen other exhaust parts in the past from other suppliers. Even the muffler inside the main box was in it's own retail box along with hangers and clamps. Pipe, muffler and clamps included Parts fit together perfectly and construction is pretty good. Nice touch for them to weld on a stainless steel straight tip, adds a lot to the finished install. The sound is pretty much like stock and there is no worry about being too loud inside or out. Nice mellow power sound... XJ runs better as the seat of your pants will tell you. UPDATE 06/2012 Muffler's rolled edges on ends now rusted through and leaking... seam in pipe leaking at bend after muffler also. 3 years since new. Good life span for the price? Seems a bit short to me, should be better in states that don't use salt in the winter months perhaps.. Replaced muffler and rear tail pipe as both were pretty well rusted out when I removed them... with current pricing you might want to do as I did and consider the same quality parts but not purchase as a "system" Thrush 17717 Turbo Muffler Walker Exhaust 55188 Tail Pipe Add a couple of 2 1/4" muffler clamps and it ends up cheaper and still with free shipping if ordered direct from Amazon. I doubt the replacements will last any longer than the Dynomax system but at least better value for same time in service. Want it to last much longer and don't mind spending three times the price... buy stainless steel muffler and pipe.

This kit actually fits 1993-2001 Jeep Cherokee XJ's, not 93-98 as the description above may say. It's a great basic replacement cat-back kit. It's no Borla, but you're not paying Borla prices either. The only parts that you may need that do not come with the kit are two metric 10mm 1.5 thread pitch bolts - and that is only if you have a 2000-2001 Cherokee. The exhaust sounds great, a little more bass to it, but no drone or rattles. Very easy install, removing the old rusty exhaust is always the hardest part. One other helpful note - if you have to replace any of the exhaust hangers on your Cherokee due to rust (the rear one in particular), they can be hard to find outside of a Jeep dealer. NAPA tends to carry them however.
