Sikky - HDR017SS

Sikky HDR017SS headers are specifically engineered for a perfect drop-in fitment in the 1993-2002 Mazda RX-7 (FD3S chassis) when performing an LSX engine swap using a Sikky LSX Swap Kit. These high-performance exhaust headers feature massive 1 7/8-inch primary tubes and a 3-inch collector with a merge bullet design for optimal exhaust flow and increased power. Crafted from 100% 304 stainless steel, the headers utilize CNC mandrel-bent tubing and a CNC stainless steel head flange for precise fitment and durability. A V-Band flange is pre-installed, and the necessary clamp and other half are included, along with new gaskets and bolts for a complete installation. For ideal spark plug wire clearance, Taylor 79013 plug wires are recommended. Sikky emphasizes that these headers are designed around their own mount kits and components, and fitment with competitor products cannot be guaranteed.
