The factory exhaust outlet on the L5P Duramax is definitely the most easily identifiable out of any diesel. Besides the outlet angle and oversized bellow, it makes it nearly impossible to give your truck an aesthetic upgrade of an exhaust tip without resorting to a complete DPF back exhaust system. Fortunately, PPE has solved this issue with this four to five inch exhaust upgrade that includes not only a 5" polished or black exhaust tip, but also the angled exhaust pipe to fit your stock exhaust to make your exhaust exit behind the passenger rear wheel.
