Plastic has come a long way since it first found its way into engine bays decades ago. But no matter how much stronger or resilient plastic becomes, it's hard to beat solid metal for parts your vehicle relies on every day. Especially if those parts carry vital coolant to and from your radiator, like the Y-pipe on your 2013-2014 RAM 2500/3500 6.7L Cummins.The plastic Y-pipe on the 2013-2014 RAM 2500/3500 6.7L Cummins is needed to connect the dual radiators and ensure efficient cooling. The Y-pipe is a critical part, but the plastic construction of the stock pipe means it's prone to cracking and failing over time.The Mishimoto 2013-2014 RAM 2500/3500 6.7L Cummins Y-pipe is constructed from cast aluminum and is precision TIG welded to ensure a lifetime of performance. Each Y-pipe is pressure tested to ensure all of your coolant stays in the system, where it belongs.Our aluminum Y-pipe features a sleek clear anodized finish and includes three high-strength t-bolt clamps to take the guesswork out of installation. And, like all of our RAM parts, this 2013-2014 RAM 2500/3500 Aluminum Y-PIpe is backed by our Mishimoto Lifetime Warranty, so you never have to worry about a failed Y-pipe leaving you stranded ever again..
