These precision-engineered Flowtech headers are leak-tested to get maximum performance and fuel economy from your engine.
They're made from .049 in. cold-rolled, flash-controlled tubing and feature Flowtech's mandrel-formed Power Plenum collector. All ports are precisely fitted and finished with durable, leak-proof, O-ringed port seals. The headers have a high temp satin black painted finish.
In addition, they come with all mounting hardware, including bolts, nuts, and premium gaskets. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom-altered parts, then it is the installer's responsibility to verify fitment.
Tech details: 1 5/8 primary tubes, 3 in collectors, 18 gauge tube, 5/16 thick flanges.
