                                 EXECUTIVE ORDER D—516—2

                         Relating to Exemptions Under Section 27156
                                      of the Vehicle Code

                           Street and Performance Electronics, Inc.
                                      Helix Power Tower

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—9;

IT IS ORDERED AND RESOLVED: That the installation of the Helix Power Tower,
manufactured and marketed by Street and Performance Electronics, Inc., 304 Smokey Lane,
North Little Rock, Arkansas 72117 has been found not to reduce the effectiveness of the
applicable vehicle pollution control system and, therefore, is exempt from the prohibitions of
Section 27156 of the Vehicle Code for the vehicle applications listed in Exhibit A.

The Helix Power Tower is an aluminum spacer plate, approximately one inch thick with
machined helical grooves on the inside ports, and is installed under the vehicle‘s throttle
body or carburetor.

This Executive Order is valid provided the installation instructions for the Helix Power Tower
will not recommend tuning the vehicle to specifications different from those of the vehicle
manufacturer.

This Executive Order shall not apply to any Helix Power Tower advertised, offered for sale,
sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

Changes made to the design or operating conditions of the Helix Power Tower, 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 Helix Power Tower using any identification other than that shown in this
Executive Order or marketing of the Helix Power Tower 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 Helix Power Tower shall not be construed as an
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 Helix
Power Tower may have on any warranty either expressed or implied by the vehicle
manufacturer.


                                                _7.


 This Executive Order is granted based on an engineering evaluation which determined that
 the Helix Power Tower will have no adverse impact on tailpipe emissions if tested in
 accordance with the Cold—Start CVS—75 Federal Test Procedure. Furthermore, On—Board
 Diagnostic II (OBD II) testing, using a 2000 4.7L Toyota Tundra, a 2001 5.4L Ford F—150, a
 2001 5.9L Dodge Ram, and a 2001 5.3L Chevrolet C1500 truck showed that the Helix Power
 Tower when installed on the vehicles does not affect the vehicle‘s ability to perform its OBD 11
 monitoring. However, the ARB finds that reasonable grounds exist to believe that use of the
 Helix Power Tower may adversely affect emissions of motor vehicles when operating under
 conditions outside the parameters of the previously prescribed test procedures. 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 Helix Power Tower adversely affect 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 Helix Power Tower will affect the
 durability of the emission control system, Street and Performance Electronics, Inc. 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.

 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 STREET AND
 PERFORMANCE ELECTRONICS, INC‘S HELIX POWER TOWER.

 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 revoked only 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 is made after the hearing that
 grounds for revocation exist.

 Executed at El Monte, California, this fif# day of August 2001.
