Street Sleeper Twin Turbo System 5.7L 6.1L 6.4L Hemi

The Hellion Power Systems Street Sleeper Twin Turbo System is engineered to dramatically elevate the performance of V8 5.7L, 6.1L, and 6.4L Hemi engines in 2006-2023 Dodge Challengers, Chargers, Chrysler 300Cs, and Magnums. This complete bolt-on system offers a scalable power increase, starting from a safe 5 psi and capable of exceeding 30 psi with an optional boost controller. The system utilizes spent exhaust energy to generate boost, avoiding the parasitic losses associated with superchargers. Constructed with American-made stainless steel piping, this system includes high-flow headers with 3-inch outlet manifolds for maximum spool and horsepower. Standard equipment features twin Hellion 62/62 turbos, dual Turbosmart/Hellion Hypergate 45 wastegates, and a Turbosmart/Hellion Race port bypass valve. Buyers can choose between a standard 3-inch core intercooler or an optional 4.5-inch race intercooler, both designed for high flow. The kit also includes heavy-duty silicone hoses, stainless steel T-bolt clamps, high-flow K&N air filters, and Hellion's exclusive oiling system. The system is built for daily drivability in all weather conditions, with no concerns about water or debris ingress. This kit is proudly made in the U.S.A. and comes with a lifetime warranty on the stainless steel piping. It is important to note that Hellion's products are sold for competition vehicles only and are not legal for sale or installation in California. All performance modifications and installations are at the customer’s own risk.
