Depending on your model of Sprinter, you may need to slightly trim the end of your exhaust pipe to prevent overheating. While it may look like our bumper should perfectly fit your stock exhaust, you must trim it just before the bumper. If you let your exhaust extend into/through our bumper, it will prevent the exhaust from having adequate heat dissipation and will heat up components surrounding the exhaust. Using a cutoff wheel to trim off the end of the exhaust about 6 inches away from the bumper will prevent any overheating. See full installation video here.
