Exhaust Headers Fit for 1997-2004 Porsche Boxster 986 Base S 2.5L 2.7L 3.2L

Performance exhaust headers designed for compatible 1997-2004 Porsche Boxster 986 Base and S models equipped with 2.5L, 2.7L, or 3.2L flat-6 engines. Featuring equal-length 1-5/8 in primary tubes, a lightweight 6-1 piping design, F1-style merge collectors, mandrel-bent tubing, and CNC-machined flanges, this header system is designed to improve exhaust flow while retaining compatibility with the original exhaust components. TIG- and MIG-welded construction, multiple O2 sensor provisions, and a polished stainless steel finish complete the performance-oriented design.
