Flowmaster 817837 2.5" American Thunder Axel Back System for 18-20 Jeep Wrangler JL with 3.6L

Quadratec Part #: 17618.0034
Flowmaster Part #: 817837
If you are planning on taking your Wrangler JL on some of the higher angled trails you might do some damage to your factory exhaust. Flowmaster has developed an axle back system that replaces your factory transverse muffler with a high tucked tailpipe giving you the clearance you need for your off road adventures. Not only will you gain added clearance but you will also get such an impressive sound they had to call it American Thunder. This 2.5" axle back system is made of mandrel bent 409S stainless steel to increase exhaust flow & help prevent corrosion giving you an exhaust system that will withstand the outdoors plus sound great also. An aftermarket bumper is recommended for this axle back system because of how high the tailpipe is tucked.

T-409 Stainless Steel: Built to resist high temperature corrosion this exhaust will withstand everything from rust to grim ensuring your exhaust will hold up keeping your Jeep sounding great and looking good for years to come.

Full Mandrel Bent Pipe: Is a process that allows the pipe to bend without creases or folds while preventing your exhaust tube flattening allowing for more of a free flowing exhaust.

Performance & Sound: Enjoy a boost in horsepower as a result from the better exhaust flow plus a head turning moderate to aggressive sound that comes out of the 3" polished stainless steel tip.

Installation: This kit comes with everything you need for installation while using some of the factory hardware also.
