This Executive Order shall not apply to any Toyota Racing Development Tubular Exhaust System advertised, offered for sale, or sold with or installed on, a motor vehicle prior to or concurrent with transfer to an ultimate purchaser. Changes made to the design or operating conditions of the supercharger, 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 supercharger using any identification other than that shown in this Executive Order or marketing of the supercharger 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 supercharger 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 supercharger may have on any warranty either expressed or implied by the vehicle manufacturer. This Executive Order is granted based on the following submitted emissions test data on a 1999 Toyota 4Runner certified to a low emission vehicle (LEV) standard: NMOG CO NOX HCHO Standards 0.100 4.4 0.4 0.018 _ ~device w/ dfs 0.059 0.6 0.2 0.003 Test results showed that tailpipe emissions with the Tubular Exhaust System installed on the vehicle met the vehicle‘s applicable emission standard during Cold Start CVS—75 Federal Test Procedure. This Executive Order is also based on On Board Diagnostic II (OBD II) testing conducted on the same 1999 4Runner truck. Test data showed that the Tubular Exhaust System when installed on the vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring.
