Product Details Technical Specs Installation Instructions
The Grand Cherokee MRT Street Race Cat Back system has a loud, deep muscle car sound and is handcrafted in corrosion-resistant T304 Stainless Steel. Base systems include T304 polished SS 4" Quad Tips and 2.5" mandrel-bent tubes. Black Ops black matte tip finish is available for an additional fee. This system is engineered for the best sound to match your Jeep and provides increased performance from the increased exhaust flow. The Version 3 Cat-Back is the loudest MRT exhaust. It has just enough exhaust presence with elevated sound to Get Noticed, plenty of opportunities to Feel the Performance, and packaged in a design without an excessive drone.

Application: 2012-21 Grand Cherokee Summit or Overland, 5.7L V8 engine.

5 of 5 Loving my MRT Exhaust November 20, 2020
Reviewed by: Dan from South Lyon, MI  
I had the team at MRT install the version 3 cat-back exhaust on my 2017 Jeep Grand Cherokee SRT a few weeks ago. What a vast improvement over the stock exhaust. It had just the deep note I was looking for to compliment the Jeep's performance. Their custom painted black tips were worth the extra cost for my desired look.

They were able to get me in within a week and work was completed same day in just a couple hours. Very professional staff, fast to respond and clean shop. Quality parts and quality work. I would definitely recommend their team for anyone looking to upgrade their exhaust.

I just installed my MRT Cat back. It sounds amazing. Really let's the 6.4 breath! Install was about an hour, spent more time with fitment than anything else. It really looks so much better than the factory exhaust. Big shout out to MRT for shipping so fast. Super impressed with the quality of the pipes. Worth every cent!
