The LS cast iron exhaust manifolds are recommended for strong performance on engines up to 500 horsepower and are available in plain as cast finish or with ceramic coatings for reduced engine temperatures and improved corrosion resistance. They also feature 304 stainless steel mating flanges to help provide a leak-free installation, and a two bolt exit flange which can be used with OEM style gaskets and fasteners for an excellent seal. Please keep in mind that spending time before purchasing the part to confirm it is indeed exactly what you need can help prevent you from ordering the wrong part. Replace/return are available if buyers receive wrong/damaged/defective items.
Anyway, by nice communications, we can find a way to make you satisfied.
