Product Description:
These Hooker BlackHeart cast iron exhaust manifolds for the popular GM LT motor has a 2.5-inch outlet and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications. Their contoured design guides the exhaust directly toward the exit port for improved flow and minimal turbulence. Cast iron construction means they will provide years of leak-free performance with less under hood noise than traditional headers and their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance. OE quality MLS flange gaskets and hardware are included to ensure excellent fitment and a leak-free installation and are available in plain as cast finish, black or silver ceramic coatings for reduced engine compartment temperatures, improved corrosion resistance and excellent styling.

EMISSIONS - 8 - This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle. Federal guidelines indicate that an engine swap is allowable if one or more of the following conditions apply:
- If there is a reasonable basis for knowing that emissions are not adversely affected as described in EPA Memo 1A
- The resulting vehicle is identical (with regard to all emissions related parts, engine design parameters and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis
- The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
- An EO legal engine swap kit is utilized (such as a GM EROD)
- The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street
Consumers are responsible for complying with laws prohibiting tampering, and for ensuring that modified vehicles are operated in a manner that complies with applicable laws.
