Jeep WK Grand Cherokee 2007 - 2008 CRD CAT back exhaust. Our kit replaces the factory CAT back exhaust for a free flowing 3" 304 mandrel bent stainless steel flanges and hardware, fully tig welded. Our exhaust will last the life of your Jeep. We use 304 stainless steel V band clamps to allow quick and easy install of our CAT back exhaust kit, that quickly mates up to the stock hangers. The CAT back exhaust allows for much greater exhaust flow when running higher performance tunes and/or upgraded turbos. Our 3" exhaust kit will give a deeper and richer exhaust note. Hear the true and raw sound of your OM642 engine. We can weld in our CCV Reroute exhaust fitting. Please allow for a 2-4 week lead time when ordering.
