CB Engineering Off Road Exhaust Pipe for the 2014-2017 Jeep WK2 Ecodiesel. Made from 304 mandrel bent stainless steel tubing with stainless steel hardware fully tig welded. Easily bolts in place of the factory exhaust from the turbo back to the rear dual exhaust. Must be run with the proper ECM tuning and for off road use only. Allows the removal of the problematic exhaust components. Two options are available; 1st is off road pipe with no bungs in it so stock sensors need to be removed or tied up under the vehicle, 2nd with machined bungs so stock sensors can be left in place.
