Review FLOWTECH 11170flt Long Tube Headers Pontiac Pair

Introducing the Flowtech 787480111708 11170FLT Tube Headers, specifically designed for Pontiac engines with a displacement between 326 and 455 cubic inches. These tube headers are a must-have for any serious hot rod or custom build project.

The Flowtech 11170FLT Tube Headers are made from high-quality 304 stainless steel, ensuring durability and resistance to corrosion. Each header tube is mandrel-bent to maintain an optimal exhaust flow, resulting in maximum power and efficiency. The header design features a 1 5/8-inch primary tube diameter, which is a standard size for high-performance applications.

These headers come with 5/16-inch NPT threaded inlets and outlets, which are compatible with most exhaust systems. The inlets are located at the front of the headers, while the outlets are positioned at the back, allowing for easy installation and exhaust system configuration.

The 11170FLT Tube Headers are also designed to work with stock catalytic converters, making them a versatile option for both performance and emission compliance. However, for maximum power gains, they can be used with aftermarket high-performance exhaust systems.

The header gaskets are included with the purchase, making the installation process even more convenient. The headers are also designed to fit flush with the engine block, providing a clean and tidy appearance under the hood.

Overall, the Flowtech 787480111708 11170FLT Tube Headers are a reliable and effective option for any Pontiac engine between 326 and 455 cubic inches. They offer superior exhaust flow and durability, making them an excellent investment for any hot rod or custom build project.
