This FLO - 878 exhaust system is a game - changer for your 2016 - 2019 Nissan Titan with a 5.0L Cummins engine. It's a 4' downpipe back exhaust that replaces the restrictive OE system. Made of aluminized steel piping, it features a single - side exit and comes with a high - flow muffler. This exhaust is super easy to install as it mounts to OE hangers and includes all necessary clamps, pre - weld contour bent hangers, and stronger flanges. It not only sounds amazing but also boosts torque, improves mileage, and enhances throttle response. Part numbers are FLO - 878 & FLO - SS878. Flo - Pro Exhausts fit all wheelbase and cab configurations unless stated otherwise.

Using this exhaust system is simple. First, make sure your vehicle is parked on a flat surface and the engine is cool. Locate the OE exhaust system from the downpipe back. Remove it carefully using appropriate tools. Then, install the FLO - 878 exhaust system by attaching it to the OE hangers and using the provided clamps and flanges. Double - check all connections to ensure they are tight. When it comes to maintenance, regularly check the clamps and flanges for any signs of looseness. If you notice any rattling or strange noises, it might be a sign that a connection needs tightening. Keep the aluminized steel piping clean by washing it with mild soap and water occasionally. Avoid using abrasive cleaners as they can damage the finish. Also, in case of any major issues, it's best to consult a professional mechanic.
