The aFe Twisted Steel 409 SS Short Tube Header is a high-performance exhaust component designed for the Jeep TJ with a 4.0L I6 engine from 2000 to 2006. Crafted from 16-gauge 304 stainless steel, these mid-length tube headers feature mandrel-bent tubing and mitered collectors to optimize exhaust flow and velocity. Incorporating aFe's pulse control technology, they are engineered to enhance power delivery across the entire RPM range. The headers are 100% TIG-welded, ensuring durability and precise construction, which results in improved engine efficiency, increased horsepower, and a more aggressive exhaust note.
These headers are a direct bolt-on upgrade for Jeep TJ models equipped with the 4.0L I6 engine within the specified years. They are designed for street and performance use, providing a significant upgrade over stock exhaust manifolds. Installation involves replacing the factory headers with these mid-length tubes, which are compatible with the stock exhaust system or aftermarket upgrades. The kit includes the headers themselves, with no additional components required. Suitable for enthusiasts seeking increased performance and a more aggressive sound, these headers are ideal for daily drivers and off-road applications alike.
