CB Engineering Jeep WK Grand Cherokee and XK Commander CRD Turbo Downpipe - Full Turbo Back. 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 DPF Race pipe and includes a gasket to seal the two exhaust pipes. This kit is slightly different from our other WK CRD Turbo Downpipe, this mates to the back of the turbo and gets rid of the factory turbo outlet elbow. This downpipe has slightly more flow than our basic kit.
