Review FLOWTECH Long Tube Headers

Flowtech 11500S Tube Headers are a superior upgrade for any performance-oriented engine build. These headers are designed to provide optimal exhaust gas flow and scavenging for high horsepower applications, making them an excellent choice for race cars, hot rods, and high-performance street engines.

The 11500S headers are constructed from 321 stainless steel, known for its durability and resistance to corrosion. Each header comes with 10 tubes, arranged in a 1 3/4-inch primary and 1 5/8-inch collector design. This size combination offers an excellent balance between power and exhaust flow.

The primary tubes are tapered to provide a smooth transition from the engine cylinders to the collector. This design reduces turbulence and back pressure, allowing the exhaust gases to exit the engine more efficiently. The collector is carefully engineered to minimize turbulence and provide maximum flow, ensuring that the exhaust gases are scavenged effectively.

Each header comes with a removable collector, making installation and maintenance easier. The collectors are also designed to bolt directly to most factory exhaust systems, making them a popular choice for those looking to upgrade their existing exhaust system without having to replace their entire exhaust.

The 11500S headers also feature a stud gasket design, which provides a better seal than traditional ring-type gaskets. This design also allows for easier installation and removal, making them a preferred choice for those who may need to remove and reinstall their headers frequently.

In summary, the Flowtech 11500S Tube Headers are a high-performance upgrade for any engine build. Their durable construction from 321 stainless steel, optimal exhaust gas flow and scavenging design, and ease of installation make them a popular choice for racers, hot rodders, and high-performance enthusiasts.
