Vehicles originally equipped with a close coupled catalyst are excluded . For the RSX and Civic (2002 through 2011 model years only) models listed in Exhibit A , the Performance Header System are made up of a one-piece, short tube style header manufactured out of 16 gauge stainless steel tubing. Individual cylinder tubes transfer the exhaust gases into a collector tube. For all other vehicle models in Exhibit A, the Performance Header System is made up of a short tube style header and connecting Y pipe manufactured out of 16 gauge stainless steel tubing . In both cases, the location(s) of the oxygen sensor(s) are unchanged from the original stock configuration . On vehicles where the existing oxygen sensor wire loom does not reach the new oxygen sensor location, CT-Engineering will provide a wire loom extension that will plug into the factory connector. This Executive Order is valid provided that the installation instructions for the Performance Header System will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. This Executive Order shall not apply to any Performance Header System advertised , offered for sale, or sold with or installed on, a new motor vehicle prior to or concurrent with transfer to an ultimate purchaser.

-2- Changes made to the design or operating conditions of the Performance Header System , as exempt by the Air Resources Board, which adversely affect the performance of the vehicle's pollution control system shall invalidate this Executive Order. Marketing of the Performance Header System using any identification other than that shown in this Executive Order or marketing of the Performance Header System for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board . Exemption of the Performance Header System shall not be construed as exemption to sell, offer for sale, or advertise any component of the kit as an individual device. This Executive Order does not constitute any opinion as to the effect the use of the Performance Header System may have on any warranty either expressed or implied by the vehicle manufacturer. This Executive Order is granted based on carryover of the following submitted emissions test data on a 2002 RSX Type-S certified to the Low Emission Vehicle II Low Emission Vehicle (LEV II LEV) emission standards: Cold Start CVS-75 Federal Test Procedure NMOG co NOx HCHO Standards 0.075 3.4 0.05 0.015 Device w/DFs 0.046 1.1 0.03 0.001 Supplemental Federal Test Procedure (SFTP US06 Cycle Only) NMHC+NOx CO Standards 0.14 8.0 Device 0.02 1.6 Test results showed that tailpipe emissions with the Performance Header System installed on the vehicle met the vehicle's applicable emission standards during the Cold Start CVS-75 Federal Test Procedure and the SFTP US06 cycle. This Executive Order is also based on an examination of the On-Board Diagnostic II (OBD II) system of the vehicle in the modified configuration. Test data showed that the Performance Header System , when installed on the vehicle, did not affect the vehicle's ability to perform its OBD II monitoring .
