(Page 1 of 3) State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—450—2 Relating to Exemptions Under Section 27156 of the Vehicle Code RACING BEAT RACING BEAT EXHAUST HEADER Pursuant to the authority vested in the Air Resources Board by Section 27156 of the Vehicle Code; and Pursuant to the authority vested in the undersigned by Section 39515 and Section 39516 of the Health and Safety Code and Executive Order G—45—199; IT IS ORDERED AND RESOLVED: That the installation of the Racing Beat exhaust header, produced and marketed by Racing Beat, 4789 East Wesley Drive, Anaheim, California 92807, has been found not to reduce the effectiveness of the applicable vehicle pollution control systems and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the 1990—19993 (1.6 L) and 1994—19997 (1.8 L Mazda Miata. Ceramic Coated Stainless Mild Steel Stee! (p/n) (pin) 1990—19993 (1.6 L) 56000 56010 1994—19997 (1.8 L) 56001 56011 This Executive Order is valid provided that the installation instructions for the Racing Beat exhaust header will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. Changes made to the design or operating conditions of the Racing Beat exhaust header, as exempt by the Air Resources Board, which adversely affect the performance of the vehicle‘s pollution control system shall invalidate this Executive Order. This Executive Order shall not apply to any Racing Beat exhaust header advertised, offered for sale, sold with, or installed on, a motor vehicle prior to or concurrent with transtfer to an ultimate purchaser.

RACING BEAT — EXECUTIVE ORDER D—450—2 RACING BEAT EXHAUST HEADER (Page 2 of 3) — This Executive Order does not constitute any opinion as to the effect the use of the Racing Beat exhaust header may have on any warranty either expressed or implied by the vehicle manufacturer. ' This Executive Order is granted based on emission test results in the modified configuration using the Cold—Start CVS—75 Federal Test Procedure and examination of the On—Board Diagnostic II (OBD II) system. A 1997 model—year Mazda Miata equipped with a 1.8 L fuel injected engine (VTK1.8VJGKEK, Tier—1, PC) was used for the evaluation of the Racing Beat exhaust header. Results from emissions testing conducted at Automotive Testing and Development Services are shown below (in grams per mile): 50k NMHC CO NOx Emission Level 0.204 11342 0.222 (w. DF applied) STD 0.25 3.4 0.4 100k NMHC CO NOx Emission Level 0.215 1.437 0.222 (w. DF applied) STD 0.310 4.2 The emission test results in the modified configuration were below the applicable certification standards with the deterioration factors applied. Examination of the OBD 11 system showed the Racing Beat exhaust header does not affect OBD 11 operation. Therefore, based on the test results, the staff concludes that the Racing Beat exhaust header meets the criteria for exempting general criteria parts. However, the ARB finds that reasonable grounds exist to believe that use of the Racing Beat exhaust header may adversely affect emissions of motor vehicles when operating under conditions outside the parameters of the CVS—75 Federal Test Procedure. Accordingly, the ARB reserves the right to conduct additional emission tests, in the future, as such tests are developed, that will more adequately measure emissions from all cycle phases. If such test results demonstrate that the Racing Beat exhaust header adversely affects emissions during off—cycle conditions (defined as those conditions which are beyond the . parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive Order shall be effectively rescinded as of the date the test results are validated. Further, if such test results or other evidence provides the ARB with reason to suspect that the Racing Beat exhaust header will affect the durability of the emission control system, Racing Beat shall be required to submit durability data to show that the durability of the vehicle emission control system is not, in fact, affected and/or that the add—on or modified part demonstrates adequate durability.

RACING BEAT ' EXECUTIVE ORDER D—450—2 RACING BEAT EXHAUST HEADER | (Page 3 of 3) ' In addition to the foregoing, the ARB reserves the right in the future to review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures of Title 13, California Code of Regulations, Section 2222, et seq. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF RACING BEAT‘S RACING BEAT EXHAUST HEADELR. No claim of any kind, such as "Approved by the Air Resources Board", may be made with respect to the action taken herein in any advertising or other oral or written communication. Violation of any of the above conditions shall be grounds for revocation of this order.. The order may be revokedonly after a ten—day written notice of intention to revoke the order, in which period the holder of the order may request in writing a hearing to contest the proposed revocation. If a hearing is requested, it shall be held within ten days of receipt of the request and the order may not be revoked until a determination after hearing that grounds for revocation exist. 4.
