Six-Cylinder Stainless Steel Headers & Link Pipes. Manufactured by XKs Unlimited from type-304 stainless steel, these free-flowing six-cylinder headers are beautifully formed and welded; they far surpass similar parts made in the UK. Whats even more amazing, however, is the price. Set includes two polished tubular headers and connector pipes to join to a standard system. Install these headers and youll enjoy a boost in power and will never have to deal with flaking porcelain again! Please note that we purposely made the link pipes on the long side, so they may require a trim on some cars. Gaskets and other mounting hardware sold separately.
