Description
EMISSIONS NOTICE: For off-road / competition use only. NOT LEGAL FOR SALE OR USE IN CALIFORNIA OR CARB-adopting states. Does not support the removal of emissions equipment.
The core of Crazy Carl's compound turbo system, sold without turbochargers so you can run your own top and bottom chargers (stock HX35/HE351, K27, HX40/S300 T3 over an S400 T6 or Holset HT3B/HT60 T6). Every pipe is TIG welded from 409 stainless and heavy-wall steel, and the layout keeps the batteries, air filter location and transmission cooler where the factory put them. Choose your truck, both turbos, hot pipe grade, filter, downpipe size and powdercoat color when you order.

Notes
- Turbochargers and exhaust manifold are NOT included.
- 98.5-07 (24-valve) kits need a 98-02 stock-geometry T3 exhaust manifold (3-piece or 1-piece); 94-98 12-valve kits need an aftermarket 12V T3 manifold. Tubular headers are not compatible.
- Steed Speed manifolds work with HE351 and other kit turbos but not with a stock HX35.
- S300 turbos on 12V/24V trucks must be machined for the factory elbow; on Common Rail trucks the S300 needs a forward-facing compressor.
- Not designed for SXE-series S400s; Smeding S400s with oversize compressor housings may not fit - confirm fitment before ordering.
- 5" downpipes are tight to the firewall and minor trimming may be needed.
