Reduce exhaust backpressure by 85% after the DPF on your 2017-2019 GM 6.6L Duramax L5P with the Banks Power 48996 5" Single Monster Exhaust System. Constructed from a 5" mandrel-bent aluminized pipe, this Monster Exhaust offers 192% greater flow area versus the stock system and the massive 6.5" x 7.5" chrome or black ob-round slash cut tip provides a 15% reduction in exhaust temperature two feet behind the tip during DPF regeneration. Since the Monster Exhaust is aimed out to the side of the truck, ambient air can diffuse the super-heated exhaust, eliminating the risk of melting a trailer which has been reported by Duramax owners.
