Our War-Header requires our AMS fuel control module, or Dobeck's EJK module, both of these modules come with the 02 sensor bypass connectors.
We also offer the War-Header in a stubby version, some like long & quiet, some short & loud, The Stubby War-Header has more off the bottom & mid range with instant response, wheelspin will happen, so the Stubby is recommended for experienced riders! The long version has smoother power with the same HP, but comes on smoother. If you want the Stubby version, note this on the comment section of your order. Long Version 93 decibels, Stubby is 103 decibels. Both versions work great with the stage II cams.
