Options and customization are important to AWE, just like it is to you. AWE engineered bolt-on mid pipes to pair with your Tread Edition Axle-back for additional sound tuning and performance. Replacing the factory mid section is a robust 3* stainless steel mid pipe available as resonated or non-resonated. For drivers looking to really uncork all of their Wrangler*s aggression should consider the non-resonated mid pipe. AWE's No CEL Guarantee, Perfect Fitment Guarantee, and Lifetime Warranty come standard.
