Selling my lightly used authentic Comptech 4-1 header since I relieved my S2000 from autocross duty and am daily driving it. Estimate it has about 5,000 miles on it and is in overall good condition. The only blemish is a shallow dent about thumb size in one of the collectors, it does not affect performance.

It is 50 state emissions legal with CARB # certification stamped directly onto the top.

The header is the 4-1 design and is no longer available directly from CT Engineering. It sells for $900 online new and paired with the intake makes approximately 12 RWHP and is quite a bit lighter than the stock header. It also makes good power in the midrange and the package has a mean sound.

Prefer local pickup in Dallas, TX but will ship as well. Email me at jkan2001@gmail.com with any questions. I've been a member here since 2002, just haven't frequented lately.

Asking $650 shipped or $600 picked up.
