Dynomax Super Turbo 39510 Exhaust System Kit for Jeep Wrangler

Honestly, I was skeptical because of the price. I wanted something quality, that wasn’t obnoxious. This muffler exceeded expectations. Packaging was perfect! I will say, I read a lot of reviews and I was worried about the difficulty of the OE removal. I was able to remove the driver side hangar pretty easily, but after fighting the passenger side for about 5 minutes I just cut the hangar off. Removing the muffler at least in my case was more of a workout than a struggle. I was able to get rotation out of it, and I took a flat head screwdriver and CAREFULLY pried up on the pinch points of the lap joint. With some tedious back and forth movements I was able to slip it off. Instead of cutting off the original clamp and reusing like some did, I purchased a 2.5” lap joint exhaust clamp which worked amazingly on this application. I used the supplied clamps for the tips, and I didn’t find the same issue a lot were having with the clamps not getting quite tight enough. Whether they fixed that issue or not, I’m not sure. It worked for me though. Another complaint I saw from other reviews was that the tail pipes were not level. Again, I did not have this issue, but I know that slightly tweaking the hangars in the right direction will fix this. The only complaint that I had was there were a few dings in the muffler body itself, which in reality doesn’t make any difference in this review. The tail pipes were perfect, the inlet was perfect, and that’s all that mattered to me. It sounds amazing. Just please take in to consideration that if you install this on a 2 door JK it will be significantly louder in the cabin, due to first, the muffler being closer to the cabin, and second, there being 3 feet less of exhaust pipe. Both of those make a huge difference in how this sounds. On a 4 door JKU (my application ‘16 JKU) it adds the perfect amount of volume, and a decent amount of throat. You only get what I guess you would call “droning” at just over 1000 rpm, and goes away at 1200 rpm. So let’s be honest… no droning. All in all, I think it’s a perfect muffler if you’re looking for a great look, with a little bit of volume. For $200.00 you can not go wrong. Beats spending $600.00+ on magnaflow, flowmaster, borla, etc.

My DynoMax showed up today. I installed it on my 2008 JKU. Very easy install. Took me less than 1/2 hour. Like everyone else who has left a comment. The hard part is getting the old muffler off. I cheated and used a sawzall to cut the hangers and the connection between the exhaust pipe and the muffler past the connection flange. I used a Dremel tool with a small cutting wheel, and carefully cut through the remaining portion of muffler attached to the exhaust pipe, making sure not to cut into the exhaust pipe. It popped right off. Total removal time was less than 1 hour. I set the new muffler on top of a box and slid the unit under the Jeep. I attached the muffler to the exhaust pipe. Perfect fit and location. I used WD40 to spray the metal hangers and rubber support hanger holes. Everything lined up perfectly and slid right in. It comes with a clamp to attach the muffler to the exhaust pipe. It also comes with two exhaust tips and clamps for the tips. I'm not sure I am a fan of the clamps. They seem heavy duty, but are a little awkward to tighten the exhaust tips onto the muffler. The sound is nice and deep, but not overly obnoxious. I bought this because it said it is made from stainless steel. My overall satisfaction will be determined by how long it lasts, but the price was right! My last muffler was a Walker stock replacement. It lasted less than 4 years and only 38K. I also keep my Jeep in the garage, which I would think would help with longevity. The passenger side hanger failed. It was also rusting, and hung down a little low. The Dynomax tucks up nice and out of the way.

I bought 2 of these, one for my 2007 JK and one for my wife's 2015 JK. I will echo much of what has been said on other reviews as far as removal and installation. I will say that both of my installs were not the same. I agree with using soap for ease of removing the old from the hangars. On the '07, it was as easy as it could be. I was able to get the old removed from the hangars with little problem. and removed the muffler from the pipe without any lube. It took a few minutes working back forth and rotating to get it off. The new one went on with zero problems and lined up perfectly. Mine does not have any chrome so I purchased a set of black tips for a much better looking match. The '15 was a different story. The right hangar was apparently a tad longer, which made it a lot more difficult to remove and I ended up just cutting the hangar. The left hanger was not a problem, just like on the '07. Other than the one hangar, the rest of the removal was like the other. This did increase the overall time for change. The new unit went on ok, but like many of the other reviews, it was not straight and level. The right pipe is a little lower and further back than the left. The fore/aft is easily compensated for with the tips, but the up/down is not. I believe I will be able to correct it but tweaking the hangar, but that will be a project for warmer weather. The sound is nice and does probably as well for a V6 as you could ask for. I would love to be able to compare it to a FlowMaster, but I can't. It has a nice tone and the volume and sound at highway speeds is hardly even noticeable. So far I am pleased with them. I've rated based on the product itself and its' install and not factored the removal of the OEM mufflers, since that has no bearing on the new product. I obviously can't attest to any longevity yet.

Like some others I painted it for rust resistance. I used some flat BarBQ pit paint and think they look great. I added this to replace a Flowmaster axle back tip. That tip sounded pretty good but it was pretty loud.... Louder than I wanted on road trips. These are not what I would call loud at all but is a bit more than stock. I will say when you get on it they sound nice and are certainly louder than stock then. I like them being mostly tame except when you put your foot into it, but still not crazy or anything. This unit does well on the trail and I didn't hit muffler at all, but did get one out pipe. The stock muffler I dented and scraped several times which is why I started changing things out. Not these however I didn't add the chrome tips. They are very nicely chromed but would stick out several more inches and I would smash them so I simply left them off. The pipe tip I hit was not bad and only flattened the button a bit. I most have come down on a rock. Nothing terrible and I rounded it out a bit with a pipe but can tell you the metal is not weak and it did better than the tip on my stock muffler. For my install the system was easy but I already had the stock system off. Having taken the old one off though I can agree that's the hardest part of the job.

Like others have said it is just slightly louder than stock. Nothing bad though. The hardest part was getting the old one off. I ended up buying the muffler hanger remover pliers. They are well worth the $$. I only got the cheap ones on Amazon, but they do the job. Some WD40 at the connection and wiggling back and forth I got the stock muffler off without any damage. I went ahead and painted it black and left the stainless tips off. These are good quality tips. So I will either keep them for another vehicle or sell them. You will be happy with this muffler and glad you saved some $$ for other upgrades.

Just got it today, couldn’t wait to install it. It was a pretty easy install... actually a VERY easy install. Getting the old muffler off was the hardest part. I painted the new system black before the install and it looks great. The clamp for the muffler itself worked fine. The clamps for the tips were too big and wouldn’t tighten down enough to hold the tips in place. I’ll go get different clamps tomorrow and install the tips. Everything looks great and both tail pipes are even and level with one another. The sound is great. A nice throaty idle and a little rumble on acceleration. At even speeds it’s a little louder than stock but not annoyingly loud. The next day I bought new clamps and installed the tips. The tips made sound even better and did quiet it down just a bit more. Very happy with my purchase. I’ve had this on my JK for about 17 months and I’m very disappointed. I have a big rust hole in the muffler and it’s getting louder. I’m currently searching for a new system to replace this cheap one.

just did this install today on my JK. those chrome tips are instantly the nicest thing on my jeep now! It sounds way cooler from inside the car, there's a low vibration at idle. Its as quiet as the stock muffler at constant RPM, but as soon as you get on it, you definitely hear it. So basically, perfect. ProTIPs-- soak not only the 15mm clamp, but also the exhaust pipe around the clamp.. it'll slide right off. Also, you can use a sawzall or a grinder to cut the hangers off right near the rubber dampers, that way you don;t have to mess with wrestling with the hangers. using blaster on the rubber hangers helps a bunch too for both removal and installation. I finished in about 45 minutes with blaster, a 15mm and an impact wrench, and a sawzall.

I am caught in the middle. Just had it installed. Took all but 15 minutes. The factory rubber hangers came right off, so need to replace, and fit perfect. Sounds great up to 40 mph, HOWEVER, once you hit highway driving you have to ask yourself is it really worth hearing that constant droning ANNOYING sound ? I mean it sounds like there is no muffler. I didn't say anything to my wife, thought I would test it out with her as a front seat passenger, and as soon as we got on the highway she said, "I think you need to get your muffler checked out it sounds terrible." Once revealed, she just looked at me at puzzled as if what idiot would want to hear that annoying loud sound during a long highway drive... And you know what, I may have to agree. I am seriously considering going back to OEM and returning the unit. Thank God I drive manual which allows me to throw it in neutral to stop the sound for a moment. However, under 40 MPH it sounds like a beast and I love it. I am updating from 3 to 1 star. I thought by driving it more I would get use to the drone sound but no, it merely convinced me to send back. Unfortunately I tossed the stock so now I have to buy new stock. Live and learn. How can so many people tolerate the highway driving and give it 5 stars.... Are they all off roading? Don't buy this if you use your jeep everyday.

Installed this yesterday. Perfect, exactly what I wanted. Looks great and the sound is just right. Not to loud, just a nice little rumble. Installation was straight forward, took about an hour, hardest part was removing the old one.

As has been said before, very easy to fit, more time taking off the old expansion chamber than fitting the new. Tail extensions are very nice indeed. Good rumble with power but in cruise disappears back to being nice and quiet. Improves the manual gear shift handling as one needs to have feedback from the motor to drive this Jeep well. In all, I am very happy indeed. Well packed and arrived on time even with Christmas in the way. I would buy another but I only have one Jeep.

All of the above

Solo recibí un muffler no sistema “cat back” descripción muy malo. embalado y de vuelta. Próxima vez escribe una descripción mejor

it arrived well packed, stainless parts secured with plastic. fits perfect, nice deep grumble. love the sound. not too loud but present. would have given it 5 stars if it would have some rust protection paint. for the price it is a excellent piece. i installed it on my 2014 wrangler within an hour. taking the old one off took longer than putting the new one on. tip for taking off an install. prepare a few days before installation with rust spray on the clamp. i started spraying it after the order day. take a very small screw driver and open a little bit the eye on the hanging rubbers to put WD40 in it. makes it way easier to slip out and in the hanger bracket. do not tighten the clamp until the exhaust is installed an wiggle it around so it can xit in the hanger rubbers. it will center just fine by itself. then tighten the clamp
