The Jonjea MT001099 LS Swap Tube Headers feature a 1-7/8-inch primary tube diameter, which is optimized for the increased power output of modern LS engines. Each header tube is constructed of high-quality stainless steel, ensuring that they can withstand the rigors of high-performance driving and resist corrosion.

These headers come with a 5/16-inch NPT threaded collector outlet, which makes them compatible with a wide range of aftermarket exhaust systems. The collectors are also equipped with OEM-style flanges, allowing for seamless integration with your stock or custom exhaust setup.

In addition, they provide better scavenging, ensuring that the engine is more efficiently expelling spent gases and drawing in fresh air for combustion.

Installation of these headers is a relatively straightforward process, thanks to their modular design and bolt-on installation. Each header comes with new gaskets, making it easier to remove the old ones and install the new headers without the need for any additional gasket material.

In summary, the Jonjea MT001099 LS Swap Tube Headers are an excellent choice for any 1967 to 1974 Chevrolet/GM LS1, LS6, LS2, LS3, or LSX engine build.
