Flow techs Y-Pipes Are Ideal For Connecting Standard Flow tech Headers To Your Stock Catalytic Converter Equipped Exhaust System.

Made from quality materials for durability, DynoMax pipe is manufactured with precision benders and fixture checked to ensure a precise fit for quick and easy installation.

Manufactured from high-temperature steel core/graphite faced exhaust material. Expanded steel core provides stability and maximum torque retention to eliminate gasket failure. Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head. Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load. Can be trimmed if necessary for modified port applications. For original equipment replacement, high performance street, drag race and oval track use.

Mr. Gasket’s Performance Header Gaskets are manufactured from a heavy duty high-temperature material, .062 inch thick, consisting of an acrylic binder system to resist high temperature. Provides excellent sealing and durability with maximum torque retention to eliminate gasket failure. While precision die-cut for an excellent fit, it can be trimmed if necessary for modified port applications. For OE replacement, higher performance street, drag race and oval track use. Fits Chevrolet 396,402,427,454 Gen IV Big Blocks with Round Ports up to 1.92 inches in diameter.

“Flow tech headers are the perfect combination of performance and value. Flow tech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16″” flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces under hood temps for increased performance.”

FLOWTECH’s emissions-friendly headers are just the ticket for those who want the best of both worlds – top performance and a clean machine. All Shorty Smog Headers bolt on quickly and easily to the factory exhaust system, retaining all stock emissions equipment, and offering maximum horsepower gains plus increased efficiency. This is a 50-State Legal header C.A.R.B. EO #D-115-16.

“Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16″” machined flanges, with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available.”
