        1 1995 Wrangler - thewolf Installation Time: Afternoon

        Obscene levels of droning

        Like one of the previous reviewers, I was drawn to this exhaust because of the clearance it offered under the Jeep. I understood that it would be loud, and am no stranger to loud, also being the owner of a c7 Corvette with a loud exhaust, but what quickly became intolerable about this exhaust was the exhaust note that made my 4.0 sound like a Honda with a coffee can exhaust, and the insane levels of drone inside the cab this thing produces. As a previous review said, the drone actually hurts your ears after driving for more than about 10 minutes. I tested it out, and the Jeep is quieter and the drone goes away if you remove this and drive around with no muffler at all! When I contacted Magnaflow about this they basically blew me off and told me "you should have known it was loud and droney". Needless to say, I'm replacing this with another system. Steer clear.

        Inaccurate description

        This is listed as aggressive sound. That's an understatement. I ride motorcycles and dirt bikes and like an aggressive sound. But this, this is an aggressive deafening sound that resonates in the cab. After calling Magnaflow customer service to see if there's a different silencer I can use, they told me it's one of their most aggressive and loudest systems. The sound note is great at idle and less than about 1500rpm with the 4.0L in line 6. Once you get over ~1500rpm the cab of the TJ is filled with a deafening drone that resonates. I measured to be ~105 dBA from the driver seat. At these levels permissible exposure is 7-15min. After a 30min drive I get out and my ears are ringing (louder than usual) even when wearing ear plugs. If it was just this loud say at 3000rpm and above it wouldn't really bother me, but it's at it's peak right in the cruising range. Aside from the system being LOUD there was no noticable performance gain and the exhaust melted my rear sway bar bushing. There appeared to be plenty of clearance, but after reading more, this is a known problem for where this turn down system dumps. Another thing I find strange is for this system Magnaflow uses a 2.25"ID inlet and 2.5"OD outlet which their customer service tells me is unique to this system. The bummer is they don't have a quieter silencer that could be put in place with out a reducer or having a fab shop try to neck down the tip. The fit and finish is nice, but I don't think the description accurately depicts just how loud and agressive this system is. The only place I could see this make sense is for a dedicated crawler if you have a hands free com system or don't mind wearing ear plugs. My ears constantly ring from years of construction work and shooting. I don't need to make the problem any worse with my daily driver. Hopefully this review helps someone get a better idea of what you're getting. If you do buy this be sure to heat shield your brake lines and sway bar bushings anywhere near the dump.

        Great product

        I have a 2005 Jeep tj, I ordered this older year one because the previous owner cut off the flange so I had to have a end that would just slip on to the existing pipe. This one worked perfectly! It sounds AMAZING!

        This sucker is loud!

        I ordered the Magnaflow Pro-Series on 31 July 2019. Estimated shipping was 2-5 business days. Shipped on 1 Aug, received it on 6 Aug. The tracking number didn’t work so I didn’t know when it was going to arrive. I worked on my removing my exhaust on 5 Aug (my only day off this week) and took me a bit of time. The nuts on the old muffler looked like a cone. Couldn’t even get a rounded nut extractor to grip it. Had to drop my pan. That has all its other challenges of having rusted bolts and holding the trans up. I finally had access to the nut but I’d be a monkey’s uncle if it was not welded on! So I had to cut it with a reciprocating saw. After I got that taken cared of, I had to cut the pipe as I can’t get it over the axle as I’m laying down under a vehicle on jack stands. So if you’re planning on doing this install, take a look at your old exhaust to see what problems it would give you taking them off. I received the cat back exhaust the next day in a neatly packaged box. Looking it over, it looks like a really nicely put together round muffler. Welds were nicely even and smooth. The brand name is stamped on two sides. The exhaust tip looks like an after thought. Just some angled down pipe with rough sharp edges. I guess it does matter as no one can see it. But I do wish they at least buffed out the edges. Earlier in the day, I had purchased some exhaust flange nuts (m10 x 1.5) to replace the one that I’m supposed to reuse. The nut size would have been useful if added on the item information. Better yet, magnaflow should include these two nuts. Installation was straight forward. Align the studs with the cat flange and loosely tighten the nuts. Install the exhaust tip on the hanger and line up the muffler and use the clamp to loosely hold them together. Once everything lines up tighten the nuts down at the flange. Btw, make sure you have a 15mm deep socket, the studs are long so a normal socket will be too shallow. Then tighten up the clamp. The test drive. When I first started my TJ in my garage, there was a very deep rumble that echoed inside the cabin. It was quite loud probably because I was still in the garage. When I backed out the tone was a nice and deep. When I started to go forward, man I can tell this is going to be loud. Not obnoxious loud but yes your neighbors will hear you loud. Sort of like taking out the baffle out of your Harley exhaust. When I got to the main road, the sound was definitely awesome going through the gears! It’s like a totally new experience. Overall I’m very happy with this cat back exhaust system. Just a word of caution, if you don’t want it loud, don’t buy this. Lol

        Love the sound

        Give it a couple days to settle and the sound is amazing. Cleans up the back end of the jeep, and adds just a little horse power. Install was a bit of an ordeal but that was because my skid plate rusted on.

        Just had this installed yesterday. It is head turning loud and I love it. Makes my ultra slow YJ sound like a beast! A little worried about getting pulled over and decibel tested... If that happens I'll send Magnaflow the ticket. :)

      5 Top Rated Questions

      will this exhaust pass state inspections?

      Is there a video of sound testing with this exhaust on a 2.5 L 1995 yj?

      I bought the magnaflow pro series cat-back exhaust but it's too load. What is a quieter option from Magnaflow or other stainless options?

      • The next step down would be the Magnaflow Performance series. The reason this system is so loud is that it dumps the exhaust under the car and the sound bounces back up into the cabin of the Jeep.

      Does the kit come with hardware such as nuts and rubber hanger grommet?

      • This comes with the 2.5" clamp, and reuses factory hardware for installation.

      Can you put a magna flow glass pack on this?

      • It would take a muffler shop to fabricate the Glass pack to this muffler system and would not be recommended.
