Ditch the factory VGT turbo in your 4th Gen Cummins for a more powerful, reliable setup. The Dirty 2nd Gen Swap Piping Kit is our high-quality take on the popular high-mount 2nd-gen turbo swap, constructed entirely of premium materials. Whether you're after increased performance or simply want a cleaner, more efficient build, this stainless steel kit makes the transition seamless. 

Later 6.7 Cummins trucks mount the turbo near the back of the engine, around the 5/6 cylinders, meaning the 1, 2, 3, & 4 cylinders all travel farther to bring air to the turbo. By switching to a 2nd-gen style manifold, you will centre the turbo between the 3/4 cylinders, giving it the best possible airflow setup.

Built with quality in mind, this kit is engineered to fit perfectly while delivering exceptional durability and ease of installation. The included downpipe mates directly with any OEM-style or Flow Pro exhaust at the factory connection point, no cutting or custom fabrication needed.

If you have an OEM CCV Filter arrangement, you will need an aftermarket CCV Delete, such as our A002 or our A108, in conjunction with our A123 Catch Can and A146 Mount Kit. When removing your VGT turbocharger, you will lose your factory Exhaust Brake. If you would still like an exhaust brake, you may want to consider an In-Line Exhaust Brake.
