    • BadAss!!!
Purchased on 4/22/2020 and Was estimated to be delivered around May 8th for delivery. Got it 4/24/2020 and blew my mind on the fast delivery. I opened the box and the Quality of the kit is top notch. My coworker and I put my 2012 Liberty on the hoist and removed my old muffler, installed this AWESOMELY EASIEST KIT I have ever installed for a muffler system in my mechanical life. We did a complete swap in about 40 minutes. The sound is awesome, a nice little Growl, NOT Over powering on accelerating from a stop. Just enough to give out a Caveman Grunt. When cruising the Intersate not Loud at all. ... show more

    • Sound clip attached to my review
The media could not be loaded. I've tried Borla and Flowmaster on other vehicles but have heard great things about Dynomax so I decided to try them out on my 2012 Jeep Liberty with the 3.7L. The first time I started my Jeep after installing, I fell in love with the sound. It has a great tone without being overbearing. I was looking for just a little louder than stock, but definitely more throaty, and that is what I got with this setup. Highly recommend. Please see my attached video clip for an example of the sound ... show more

    • Good product
Good replacement-makes my Nitro sound like new and full of power again. I replaced my original that was 5 years old and burnt out at the tailpipe/resonator. Be aware that the connector for the muffler is quite different on this aftermarket from the OEM-the original is a welded clip on the connection before the muffler while this replacement is just a clamp with a double bolt and the connecting pipe has no clip. This was somewhat confusing at first because it appeared that it needed to be loosened whereas it did not come off at all. My process was simple-I cut off the existing muffler and connecting pipe with a reciprocating saw as the OEM clamps were rusted and it was a tight fit-you won't need them anyway. Then with a second pair of hands-which I highly recommend-the unit was assembled from front to back and put into place then tightened down. I spent about 90 minutes on this only because of the rusted OEM parts-otherwise it would have been a 60 minute job. ... show more

    • Perfect for 08-12 Jeep Libery KK
First off, I had this professionally installed and welded instead of using the clamps that came with it. I love this exhaust! It has a great exhaust note, not too loud but throaty performance sound! Also, my jeep feels like it gained pep and better acceleration overall (combined with a K&N filter). My mileage is also improved, as per scangauge II. Thanks Amazon and Dynomax! ... show more
