Product Description

The PLM Power Driven K-Series 4-2-1 Header is engineered specifically for the 2004–2008 Acura TSX and 2003–2007 Euro-spec Honda Accord CL7/CL9, delivering a proven increase in performance where it matters most. Designed with a long-tube Tri-Y (4-2-1) configuration, this header improves exhaust scavenging to maximize low- and mid-range torque while maintaining strong top-end power—making it ideal for both spirited street driving and performance-focused builds.

Constructed from high-quality 304 stainless steel, this header features precision mandrel-bent tubing, a CNC-machined manifold flange, and a true 2.5-inch collector for optimal exhaust flow. The thick 3/8-inch flange ensures a proper seal and long-term reliability under high heat conditions. A two-piece design allows for easier installation and improved fitment compared to one-piece long-tube headers.

As one of PLM’s best-selling K-Series headers, this Power Driven model is a trusted choice among enthusiasts looking for a bolt-on performance upgrade with excellent value, durability, and real-world gains.
