The extra connection length for your longer RAM
Complete the Kooks header-and-Y-pipe installation on the specified longer-wheelbase RAM with 35103400. This 3-inch 304 stainless extension is for the 5.7-litre Crew Cab with a 6-foot-4-inch bed and 149.5-inch wheelbase.
SKU: 35103400
Match the cab, bed and wheelbase
The confirmed extension application includes 2013-2018 RAM 1500 and 2019-2023 RAM 1500 Classic in that specific configuration. Those measurements matter; a shorter-wheelbase truck does not use this extension on the same basis.
Use the matching front exhaust
Kooks headers and a matching Y-pipe are required. For a Classic, choose a Y-pipe with its own confirmed Classic application rather than carrying the extension’s years over to another part.
Matching products
For your 2013-2018 RAM 1500 5.7 Crew Cab with a 6-foot-4-inch bed and 149.5-inch wheelbase, pair the RAM Competition Y-pipe with this extension and the matching Kooks headers.
