What does a 2nd Gen swap kit include?
Check the included-parts list on the kit for your truck year. A Praxis base piping kit is not a complete turbo package: the turbo and exhaust manifold are additional components. Our current high-mount piping kits start at $1,800. Selecting optional components changes the price.
Base kit listings include a 5-inch intake, dry filter, 3-inch intercooler piping, 4-inch downpipe, stainless spacer, boots and clamps, and oil feed/drain lines with fittings. Confirm the exact configuration on the product page before purchasing.
Choose your truck year first
- 2003–2009 Dodge Ram 2500/3500, 5.9L or 6.7L Cummins: choose piping only or add the available turbo, housing and manifold options. Select 2003-2007 or 2007.5-2009 before adding to cart.
- 2013–2018 Ram 2500/3500, 6.7L Cummins: choose piping only or add the available FIS turbo, T4 turbine housing and manifold options.
- V2 2013–2018 Ram 2500/3500, 6.7L Cummins — traditional piping layout: choose the traditional 2nd Gen piping configuration with the same turbo, T4 housing and manifold options as the original 2013–2018 kit.
- 2019–2024 Ram 2500/3500, 6.7L Cummins: choose piping only or configure the available turbo, housing and manifold options.
Have a 2010–2012 truck, a different model or a custom combination? Contact Praxis to discuss fitment before ordering another year’s kit.
Piping only versus a configured package
Already have a turbo and manifold? Send us their exact make and model to confirm compatibility. On listings with package selectors, choose “NONE” for the turbo, “None” for the housing and “No” for the manifold when supplying your own compatible parts.
Need a turbo and manifold? All four kit pages offer FIS 464/83, 467/83 and 472/83 options, T4 turbine housings and an optional one-piece stainless steel gated manifold. Check the product’s current choices and total price. Send us your towing use, driving goals and existing fuel-system details for help choosing a combination.
For the 2013–2018 kit, fitment is guaranteed only with the one-piece ITI or Smeding stainless steel T4 manifold described on that listing. Do not assume a different manifold has the same fitment. Confirm your exact combination with us.

These existing Praxis product photos show an installed 2013–2018 configuration. Optional components shown are not automatically included in the base kit.
Why choose Praxis piping?
Every tube component uses Stainless Bros 304 stainless steel. Welded assemblies are TIG welded, back purged and built in fixtures for consistent fitment. The original 2013–2018 and 2019–2024 kits use a two-piece intercooler tube with hump couplers to accommodate engine movement and allow removal in sections for service access. The V2 2013–2018 kit offers a traditional 2nd Gen piping layout instead; review that listing when comparing configurations.
Lead time, finish and shipping
Allow 2–4 weeks before shipping, depending on the turbo selected. Contact us to confirm timing for your configuration, especially if your build has a deadline. Ask about custom powder-coating colors, pricing and timing before ordering.
Free standard shipping applies to orders over $1,500 in the contiguous U.S. See the shipping policy and refund and return policy. Made-to-order and custom items are not eligible for return, so confirm fitment before purchasing.
