Vendor: Flo~Pro


Fits: 2013-2018 Dodge Ram Cab & Chassis w/ 6.7L Cummins

Looking to remove the OEM CAT & DPF in your 2013-2018 Cab & Chassis Cummins? The FLO~PRO FLO-21126 / 21127 Test Pipe removes them and replaces it with a 4" straight pipe to remove the restriction in your exhaust and allow it to flow more freely.

The Cummins Cab & Chassis requires you two pipes to fully delete the emissions system. If you measure 70 inches from the back of the cab to the centre of the rear wheel you'll need the FLO-21128 - if you measure more than 70" you'll want to order the FLO-21129.
