The Doug Thorley Cat-Back Exhaust System juices-up your Jeep with free-flowing power. It utilizes custom CNC mandrel-bent 16-gauge aluminized steel tubing to eliminate restrictions and backpressure. The mandrel bending provides a full diameter tube thru all bend so there are no choke-points in the system... unline the factory exhaust which has a bunch of bend that squish the tube diameter way down.

The system also includes a high-performance Thorley muffler. Your Doug Thorley Cat-back Exhaust carries a Lifetime Warranty for the original owner!

Your Jeep came with ample horsepower and torque for the average grocery-getter driver. Doug Thorley Exhausts have never been much for average, though. Thorley's decades-long mission has been to make stock exhausts look inferior. This is where Doug Thorley Exhausts come in for your Jeep. Using 16-gauge aluminized steel tubing, custom CNC mandrel bending, and a free-flowing muffler, a Thorley Exhaust adds instant punch at the pedal. It provides loads of low-end pulling torque, too.

All Cat-Back kits drop-ship direct from Thorley (Summit Industries)!
