Default aFe MACH Force XP Axle-Back Exhaust

4 exhaust systems later, I have found one that will be staying on the Jeep.

My previous threads here:
https://www.jk-forum.com/forums/modi...-video-278299/
https://www.jk-forum.com/forums/modi...-video-277523/


I spent a week looking everywhere on the internet trying to find anyone who posted their experience with the aFe axle back, but found nothing, so I decided to risk it and post my findings.
Of the previous systems I had installed, I liked the rock crawler the best, but the drone on the highway was too much for the wife.
My goal was to find a system that got rid of that monster ugly stock thing, re-locate or move the stock muffler, and have no drone on the highway.
This system has achieved all three of these goals.

The aFe axle back is much smaller and lighter than stock, sits in a "high tuck" position that allows more rear end clearance, and has no drone while cruising on the highway.
For those looking to make more "noise", this system is likely not for you.
While it is louder than stock, it is not by much. You can definitely tell it's there when you hammer down the gas pedal, but it's only about half as loud as the other after market system's that I've tried on the Jeep.
Also *note* that I still have the stock resonator installed. I did not wish to mess with it after taking a 700 mile trip to Michigan this past weekend and getting the thumbs up from the wife on the noise level.

aFe part number is: 49-46219
Exhaust Systems Axle-Back MACH Force XP EXH 2.5in Axle-Back; Jeep Wrangler JK; 07-13 V6-3.6/3.8L 49-46219 - aFe Power
I purchased from AutoAnything for $229 shipped after 15% coupon


My pertinent Jeep configuration is as follows:
2013 JKU
3.6L Pentastar Engine
3.73 Gears
Automatic Transmission

The bottom line on this is, if you want to get rid of the ugly stock muffler with something that will be almost as quiet and gain some clearance in the rear, this is your answer.

I hope this helps anyone else who has been trying to find information on this system.

Super easy.

A little WD-40 on the rubber hangars, and from start to finish was only about 15 minutes.

I've had the 3 inch version for 2 years now and love it. It makes the jeep sound like a jeep not a soccer mom car

This is not the same system, and you have a different engine.

Just pointing it out now since that's how most exhaust threads on here seem to go.

And thanks for reminding me I needed to put that in the OP

Thanks for the recommendations, I snagged one from autoanything for 220 shipped

Running without carpet/drain plugs year round so this is exactly what I'm looking for

Installed it today

Took about 2 1/4 hours

More than 2 hours was getting the stock exhaust off with soapy water, wd40, grease, ball joint separator (don't ask), and a large cresent wrench. And that was just the drivers side. Passenger side I said fugg it and cut off the hanger with a dremel (only cut half into the hanger, it simply broke off after that with some elbow grease). To remove the muffler from the tail pipe, just a ton of wd40 and rotate back and forth.

Hint: if you do this in your garage, put some cardboard down to soak up the wd40 (doh!)

Took 15 min to install the axleback. Greased the hangers and they slid right in

Sounds great, somewhat noticable and I have top off, carpet off, drainplugs out. Sitting in the driveway, I had to tell myself I heard it. Drove around the block and it is not bothersome at all. My wife, kids, dog, and neighbor will appreciate that it is not booming loud. Very Very subtle if you ask me

I've got about 1000 miles on mine so far, still happy with it.

As an update to this, I still have this system on my Jeep and it will be staying on for the foreseeable future.
Actually, after a couple thousand miles it has toned down a little bit quieting it a little more than it was day 1.
Loving this exhaust.
