These Flowtech cast iron exhaust manifolds have a 2.25 inch outlet, natural cast finish and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications at a budget friendly price. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.
Features:
- Intended for GM LS engine swap applications where durability and leak-free sealing is desired at a budget-oriented price
- 304 stainless steel mating flanges included (mating flange fasteners are not included)
- 2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
- 2 bolt exit flange configuration matches 2010 Camaro (also the same as the E-rod exhaust manifolds) which can be used with OE gaskets and fasteners if desired, for an OE quality seal
- Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
- Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
- Available in plain as-cast finish or with black or silver ceramic coatings for reduced engine compartment temps and improved corrosion resistance
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
