CB Engineering Jeep WK Grand Cherokee and XK Commander CRD Turbo Downpipe. This replaces the factory downpipe for a free flowing 3" 304 mandrel bent stainless steel with stainless steel v band fully tig welded. Includes 304 SS fittings for the 02 sensor and the EGT sensor. The turbo downpipe reduces EGT's and allows for much greater exhaust flow when running higher performance tunes and/or upgraded turbo. Designed to mate up to our Race pipe and includes a gasket to seal the two exhaust pipes. This kit keeps the factory turbo outlet elbow. This kit is our standard kit and is easier and quicker to install than our Full Turbo Back Kit. This item is built to order. Lead times can be up to 3-6+ weeks. All sales are final.
