This is a DPF-Delete system designed to eliminate the diesel particulate filter (DPF) improving horsepower, torque, throttle response, turbo spool up time and mileage. These systems are constructed from 4" 409 stainless steel and come with two thermocouple bungs, two pressure tap bungs, band clamps and OE style hangers for an easy installation. To finish the system a 5" 304 polished stainless steel exhaust tip is included. These can be ordered with or without a muffler.
