2015 or 2015.5?
2015 is a split year. The 2011-2015 downpipe is secured to the turbo-direct pipe using a V-band style clamp. The 2015.5-2016 uses a 3 bolt flange style connection. Be sure to visually verify the clamp style your truck is equipped with.
Features:
The turbo direct pipe on some of the 2015 models has a 3-bolt flange instead of a V-band clamp. These kits will only fit models equipped with v-band clamp and will not work for trucks equipped with the 3-bolt flange off the turbo direct pipe!
The exhaust pipe material is T409 stainless steel. A common misconception: unlike T304 stainless steel, T409 stainless steel is still magnetic. So if you are checking to see if you really have stainless steel, keep in mind that the magnet will still stick to it.
Fuel mileage - Expect a significant increase in fuel mileage. If your DPF is clogged, you probably average about 13-14 miles per hour. More or less depending on the degree of clogging. After removing the DPF/CAT, expect a combined mileage of 18-19 mpg. Big tires and poor driving habits will result in lower mileage.
