Show original supplier description
The MMI Speed Shop Twin Turbo Kit is a turn-key performance solution designed for 1999-2006 Chevrolet Silverado and GMC Sierra trucks powered by 4.8L, 5.3L, or 6.0L Vortec V8 engines. The system includes OEM-quality cast exhaust manifolds, downpipes, mandrel-bent TIG-welded aluminum intake piping, hybrid T3/T4 turbochargers, and a bar-and-plate front-mount intercooler. Performance tuning is highly recommended, and the system is designed to provide power gains starting at 8psi of boost. Users should note that new spark plugs and upgraded poly or solid motor mounts are recommended. The system connects to the factory exhaust, eliminating the need for custom fabrication. Please note that this product is not for sale in California or New York, and it is legal in California only for racing vehicles that are never registered or licensed for highway use.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
