Fitment — check before ordering

• 2019–2024 Ram 2500/3500 with the 6.7L Cummins, configured for a high-mount 2nd Gen turbo swap.
• Confirm your exact turbo and T4 manifold combination before ordering, especially if you are supplying your own components.
• Already have a turbo or a different manifold? Contact Praxis before ordering with your truck year and exact turbo/manifold combination to confirm compatibility.

What’s included in the base kit

• 5-inch intake with hidden MAF and IAT sensor locations
• Dry air filter
• Two-piece, 3-inch intercooler tube
• Two 4-inch-long, 3-inch-diameter hump hose couplers — one at the center connection and one at the intercooler
• 4-inch downpipe
• 1/2-inch stainless steel spacer
• Required boots and clamps
• Oil feed and drain lines with fittings

Choose your package

• Piping only: choose “NONE” under FIS Turbo and “None” under Turbine Housing. Choose “No” for the manifold if you are supplying your own compatible manifold.
• Add a turbo: choose FIS 464/83, 467/83, or 472/83, then select the T4 turbine housing for your setup: .90, 1.0, or 1.1 A/R.
• Add a manifold: choose “Yes” under Add 1-Piece Stainless Steel Gated Manifold.

Why choose Praxis piping?

• 304 stainless steel: every tube component is made from Stainless Bros material.
• TIG welded and back purged: each welded assembly is built in a fixture for consistent fitment and clean welds.
• Movement built into the design: the two-piece intercooler tube and hump couplers accommodate lateral and axial movement as the engine moves under load.
• Easier service access: the two-piece tube can be removed in sections when working on other components.
