This is a 5" Downpipe back single exhaust system that compares to the 653NB or SS653NB system by FLO-PRO and similar systems by MBRP and Jamo for the 2011-2022 Superduty trucks. This kit allows you to remove the restrive OE exhaust system, it will open up your exhaust system and lower your EGTs. This exhaust system does not include a muffler and is intended for race trucks only. Comes with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you cruise through the installation process. This kit not only sounds great, but will improve fuel mileage, throttle response, and torque in your 6.7L.
