This exhaust system was a perfect fit for a 2011 jeep liberty limited. In all, it took about 2 hours from beginning to end in the my driveway, by myself and in all fairness, the first hour was spent cutting the old exhaust system out. All of pipe followed the factory routing and the hangars and brackets fit perfectly in the factory locations.The exhaust system has a nice little growl to it but it's not loud or obnoxious in any way. I can tell that it's much less restrictive than the factory system due to improved throttle response and the jeep seems to have a slight bit more power.Last but not least, the polished exhaust tip peeks out under the rear bumper and looks nice.Hopefully I don't need to replace it anytime soon but if I had to, I would buy this again.

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.

After receiving the first one arrived missing the muffler, new one arrived complete. It's not a true cat-back system, need to cut pipe in front of muffler. Once old pipes and muffler were removed the new system went in place nicely. One of the clamps broke, ended up welding pipes on both sides of the muffler. Sounds nice, a little louder than stock. If you're looking for a replacement system, this is a good choice. Great price for a stainless steal system.

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.

First off, I had this professionally installed and weldedinstead of using the clamps that came with it.I love this exhaust! It has a great exhaust note, not too loudbut 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!

The kit was complete with all required clamps and pipes.I installed a regular Walker muffler and tailpipe 2 years ago and it completely rotted out (broke away from the muffler, tailpipe beyond resonator fell off, resonator and mid-pipe broke apart while removing).I selected this system because it is listed as all stainless steel construction.It all fit in place perfectly - no issues or adjustments required.Sound is slightly louder than stock but I don't find it offensive. Interior droning is minimal. Not bad considering you could roll a golf ball right through the muffler. Mandrel bent tubing looked to be of decent quality and the chrome tip is a nice touch.
