Jeep Wrangler JL 2018 Catback Exhaust System. Expertly engineered and trail tested catback delivers that deep growl at low RPMs while trail riding. Optionally you can remove the axleback while rock climbing for maximum clearance. Includes resonator delete tube to remove mid resonator if your looking for a more aggressive sound. This American made system is TIG welded and made with 2.5 304 Stainless Steel to resist corrosion and last a lifetime or at - least until you misjudge that boulder. JeepLife We finished it off with two 4 slash cut tips that are polished to a mirror finish. This system includes everything you need to install except tools and a cold six pack. It bolts right up to the factory tubing and shouldnt take more than 4 hours to install for the average Jeep owner. olllllllo.
