On3 Performance (2009 – 2023) Dodge Challenger / Charger / Chrysler 300 / Magnum 5.7L - Shorty Headers

These are designed to be direct plug and play to your factory manifolds. Making this an easy bolt on solution to get a better flowing manifold without changing your whole exhaust setup. These work with stock or aftermarket mid-pipes that bolt to stock manifolds. These are also used for guys running our low mount twin turbo kit on their 6.1L, and 6.4L cars. These will bolt directly to the 6.1L and 6.4L engine, the only difference being the outlet flange and size is different. Our kit is designed around the 5.7L outlet flange which is why these are a great option for the guys running that combo. For the NA guys these are a 1 3/4" primary allowing increased flow over stock, this is a 10-20hp gain depending on the mid-pipes being used. These headers retain your stock catalytic converters and factory 02 sensor locations for a direct bolt-on installation which requires no cutting or modifying. 3/8" thick flanges to prevent the chances of warpage over time.         Emissions Disclaimer: This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles.
