Reviews: Dynomax Stainless Steel Axle-Back Exhaust System - 39510

Fairly easy to install but did require some bending of hanging bracket to get pipes even. Noticed some performance improvement and sounds great.

Muffler and pipes sound GREAT! Nice deep tone and rumble. Not too loud but deffinately noticible. One thing about the install you will need a new exhaust clamp since Chrysler devided to weld the one to the original muffler (lame). Chrome tips were not included in my box but after only 1 call to 4WD they are on the way. Great job Dynomax and 4WD deffinately worth the price.

I wasn't to sure about this when I ordered it but for $180 figured why not. Glad I went ahead and ordered. This product give my jeep a lower sound and almost sounds like a V8 or that it has a cam. Louder inside the jeep than outside. I don't believe you will be disappointed with this muffler. Well, unless you are a soccer mom!

It sounds great. Nice grumble!! It's not too lound.. It's the perfect amount for a jeep.

Modifications had to be made to factory exhaust. Pipe must be shortened to fit. Brackets on muffler also needed to be modified since they were bend incorrectly. Once installed though they sound great and look even better with the dual exhaust.

Sounds good,perfect fit.

Hard to get old one off, easy to install

If your looking to add that certain something that separates you from the rest.. look no further, sounds awesome a nice deep tone that turns other jeep owners heads! not to mention the easy installation, perfect fit and great price... any reviews that say its too loud? well all i have to say is... i didnt have to turn up the music.

Very easy to install, it has a nice low tone too it,,at idle nice low rumble sound , just what I wanted, you cant really notice at regular driving speed, gives a nice sound to the jeep now,,it now has Balls...love it..I painted it Rustolium high heat Black before installing it..looks great..The Chrome tips perfect fit, if they don't tighten all the way , just remove the center nut thing and all tight :)

an hr. after it arrived it was on my JK. the sound is just about the way I like it. I believe it has more power, in fact when I hit 2nd gear the rear tires chirped. That's a first! Now to the strip.

easy to install and fits perfect. has a deep tone.looks great.

This item was installed on my 2013 Jeep Wrangler and was a snap to install. Everything fit the way it should. After driving the vehicle for the first time after installation I was amazed at the increase in torque and horsepower. It turned a vehicle that was ok to drive before the installation into one that is now a hell of a lot of fun to drive. Acceleration, passing power and low end driveability have all been greatly improved. I would recommend this set up as the first thing that any Jeep owner with the 3.6 liter V6 should add to his or her vehicle.

Bought this for my 2008 Wrangler JKU. It was supper easy to install. Everything lined up and had it on in about an hour. The only issue was getting the old one off cause the clamp was rusted.. Used my Dremmel and it popped right off. I get great response with the new muffler and since the jeep 3.8 engines aren't so great, this was a nice improvement. Plus I notice I'm getting about an extra mile or two per gallon. Love the throaty sound this muffler has too...my wife unfortunately is not a fan, but she doesn't drive it anyway....

My shop said it was easy to install and they only had trouble with one of the clamps that was provided to secure the exhaust tips. This system provides a low growl at low speeds and when under a load, but mellows out at cruising speeds.It seperates you from the everyday crowd.

Easy to install. Sounds good. Not too loud, but let's you know it's running.

Love the easy installation. Good quality product. Wish the clamps for the tips were better quality. Bolts broke when tightening to attach tips. Had to weld on which looks better but jot planned. Highly recommend muffler!

This product is definately worth the price I paid. I have a car lift so this made my install a little easier. The passenger side hanger is not even with the driver side so it sags a bit on the right. Clamps for the tips are nice but seem to not hold tight enough even when they are tightened all the way. May be wrong size. I finally tack welded my tips so I wouldn't lose them. Be aware, when you have the top off your jeep these Dynomax mufflers have a resinant frequency that is not pleasant at lower rpm's. Once a 35mpm or 65mph, common speeds it's okay. I wishe they took a bit more time to ensure the assembly was jigged accurately before welding as the sagging right side drives me crazy.

sounds good

easy installation, good looks, improved fuel economy and power. may be a little loud for some
