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
- Nickel plated 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 the E-rod exhaust manifolds for a factory like fitment. This allows the use of factory gaskets and fasteners if desired, for an original quality seal and fitment
- 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
