Under the hood, Nelson keeps the mostly stock engine clean with a few minor details including a K&N air filter and dual electric fans. The dually breathes easier thanks to large 3" exhaust and Dynomax muffler, with the exhaust ending and turning down before the rear axle.  Nelson wishes to thank his friends and family and Eric Arrington at KUSTOMWERKS for all of their help and support in getting his dually where it is today.
