PRODUCT OVERVIEW

Flowmasters new American Thunder cat-back system for the Jeep Wranglers is perfect for the person looking for maximum performance and ground clearance from their exhaust system. This 2.50" system features a 409S stainless steel mandrel bent tailpipe with a 3.00" polished stainless steel tip and fits both 2 and 4 door models with the 3.6L and 3.8L V6 engines. This system replaces the factory transverse muffler and relocates the Super HP-2 muffler behind the factory catalytic converter, providing a moderate to aggressive sound level. This relocation allows for better ground clearance when driving off-road. Because the tailpipe is tucked up so high, an aftermarket metal bumper is recommended. The exhaust system is manufactured in the USA and is covered by Flowmasters Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.

Installed on 2014 JK Rubicon X

So I installed this on a 2014 JKRX about a month ago and I have been waiting to post a review. The sound and ground clearance is awesome! My mileage has dropped 2 - 4 MPG and I am not driving it with a heavy foot due to the better sound of this system over stock. The install took way too long as it seemed that I was the first person (according to Flowmaster tech support) which struggled with a two-door install. I ended up cutting 1.75" off of the first pipe connected to the stock y-pipe to make it fit. The 3/4" clearance recommended by flowmaster is very difficult to achieve over the rear sway bar and below the body at the rear axle
