This upgrade increases horsepower, torque, and turbo efficiency, while also delivering a deeper, more aggressive exhaust sound.

Q: Does this downpipe replace the factory catalytic converter?

Q: Is this downpipe compatible with a turbocharged setup?
A: No, this downpipe is designed for non-turbocharged 2012-2018 Jeep Wrangler JK 3.6L engines. If you have installed an aftermarket turbocharger on your Jeep, you will need a downpipe specifically designed for a turbo system.
