Fitment

-Fitment:
For 2011-2015 Chevrolet Silverado & GMC Sierra 2500 & 3500HD 6.6L Duramax pickup trucks. Short bed crew cab and long bed crew cab. Will not fit Cab & Chassis trucks.
-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 is constructed from T409 stainless steel, which is commonly mistaken as non-magnetic like T304 stainless steel. However, it should be noted that T409 stainless steel remains magnetic and can be verified by its attraction to a magnet.
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.
-Tuner required
Removal of DPF, CAT, SCR and/or DOC includes removal and elimination of emission related sensors. A tuner with DPF removal capability is required to prevent engine warning lights or diagnostic trouble codes. If you don't already have a tuner with DPF removal capability, We recommend the Minimaxx tuner for DieselTok stores.
