Has magnaflow fixed the problem with this system as far as fitment? I know everyone was having an issue where it would not slip over the oem pipe and would have to be widened to fit. Any thoughts on this?

I just installed. Had to cut 2” of straight pipe that connects to rear of muffler. The two inches was cut off the farthest rear end of that straight pipe. Fit was excellent then. Problem, seems to be an exhaust leak. Super loud directly under drivers seat. Figuring it must be the oem clamp that is reused. Any options/ideas on how to fix? It’s the wife’s Jeep. She hates how loud it is. I tried to play it off but literally had to roll up the windows it was so loud going up the hill out of our neighborhood.

So, I ordered the cat back black magnaflow and installed it today. It could not have been easier. Took maybe 10 minutes to get the old one off and about 10 minutes to get the new one on. The pipe slipped over the factory pipe with no issues. Did not need to expand the pipe at all. It's almost perfectly lined up, but I may take a few minute to adjust that tomorrow. Could not be happier. It's slightly louder than stock but with a much better tone and no drone. Looks great, smaller than stock and lighter. Great system. They must have fixed the issues they were having. I've had magna flows on my other jeeps, Mustangs and Raptors and they've always made a quality product.

It’s all about when your Jeep was built, if I understand correctly. When was yours built?

Mine was built late March of 2018.

Email exchange I had with Magnaflow regarding fitment issues. There are more than 10 out there. They say its fixed...if you recently buy one, please report back on fitment.

David,

We do not sell anything directly to the public at this time. Out of the 1,100 parts produced there were only about 10 with that issue. Distributors were instructed to inspect and return any parts with the wrong size inlet. I would not worry about getting one that doesn’t fit. If you have any fitment issues with the part you purchase you can email or call me directly and we will make sure you are taken care of.


Let me know if you have any other questions.



Best Regards,

Actually, if there maybe a few out there that are bad, how does the public know that the one they are buying is or has been corrected so that the pipe fits now? Have you instructed dealers to pull the first run? How would we know?

Hi Dave,

We had a handful of these systems that were not expanded correctly in our first run, but this issue was already fixed. There may be a couple of them out there at distribution centers, but everything we have in stock is correct.

Hello,


I am interested in this product however I am a member of a Wrangler JL forum and most consumers are saying that this muffler will not fit the OEM pipe. They need to take this muffler axle back product to a muffler shop to have the connector flange widened on your muffler.


Why is this? Have you fixed the issue and made changes to this muffler so that it will fit?


I have seen feedback from consumers online (Amazon, forums, youtube etc) and your muffler clearly is the same size as the OEM pipe and therefore is not large enough to fit over the OEM pipe.


Have you addressed this issue so that I may report back to the JLWranglerforums.com administrator or do I simple tell everyone to avoid purchasing this?


There is a Magnaflow employee who is a member of our site who refuses to answer questions regarding fitment which is not acceptable.


Thank you for the help,

I ordered Magnaflow 19388 from Amazon last week, installed on Saturday with no issues. Took me 30 minutes and I'm very happy with the fit.

I am hoping you can help with this..

I have an aftermarket steel bumper that sits lower than the OEM one. What I'm concerned about is the tips clearing the bottom edge of the bumper. The bumper I have has a lower edge that is in line or comes down to where the hitch pin hole is. So...any aftermarket axle back's exhaust tips must not be higher than the bottom edge of the pin hole if that makes sense. Can you send me a side shot showing where the exhaust tips top edge is in relation to the hitch pin hole??? I would greatly appreciate it...

Does this help? There is a little bit of adjustment to drop the tips down but not much. You may be able to find longer rubber hangers to drop the exhaust down to where you want it.

It does thank you. I might have to look at longer rubber hangers if I choose this one. From the pics, it looks like the top of the tips will strike the bottom edge of my bumper.

It may be fixed but I think every member in this forum that has bought something has had an ID sizing or length issue. Their quality has been poor to say the least for the JL. Lots of other companies out there now that will get my $

Hey guys...I've been looking into the Magnaflow exhaust for my new JL Rubicon. Really like the look of the black dual exhaust, and the sound clips I've found make it out to have a nice sound w/o being overbearing. For those that have had the system on theirs for a little while now, are you still happy with it? Any issues with drone?
