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 are available with either a high satin black painted finish or a silver luster ceramic coating. 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.

Easy installation just wish It didn't come with a few scratches and had to repaint over them but other than that awesome product. I also have some flowtech headers on my 91 Camaro and they sound great. I know flowtech don't make late model headers there from a 69 Camaro and fit well just a few mods.

Summit RacingSummit Racing Verified Purchase

Good headers at a great price. I recommend this if you are looking for a better alternative than exhaust manifolds, and they are cheaper than other headers available. However, when I received mine they had already had rust on them and the pipes were dented in spots, (not for performance boost), and the gasket surface for the reducers were not flat but bent. ...read more

This was a great purchase and installed without many issues. The only thing that was difficult was installing it with the motor in, and would be easier with motor pulled to access bolts. Angled-boot plug wires work best for this part, regardless of installation instructions.
