                          Relating to Exemptions Under Section 27156

                                   SLP Performance Parts, Inc.
                                      SLP PerformancePac

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—02—003;

IT IS ORDERED AND RESOLVED: That the installation of the SLP PerformancePac,
manufactured and marketed by SLP Performance Parts, Inc., 1501 Industrial Way North, Toms
River, New Jersey 08755, 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 1999 through 2006 model year General Motors trucks equipped
with a 4.8, 5.3, or 6.0L engine, as listed in Exhibit A which is attached hereto and incorporated
herein.

The SLP PerformancePac includes replacement rocker arms with a 1.85 rocker ratio, high flow
air intake, 16 gage shorty style headers, exhaust system downstream of the catalytic converter,
and a hand held programmer with no user adjustments to reprogram the vehicle‘s ECU.

This Executive Order is valid provided that the installation instructions for the SLP
PerformancePac will not recommend tuning the vehicle to specifications different from those
submitted by the device manufacturer.

Changes made to the design or operating conditions of the SLP PerformancePac, 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 SLP PerformancePac advertised, offered for sale,
sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an ultimate
purchaser.

Marketing of the SLP PerformancePac using any identification other than that shown in this
Executive Order or marketing of the SLP PerformancePac for an application other than those
listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air
Resources Board.

This Executive Order does not constitute any opinion as to the effect the use of the SLP
PerformancePac may have on any warranty either expressed or implied by the vehicle
manufacturer.


                                              _2


This Executive Order is granted based on emission test results in the modified configuration
using the Cold—Start CVS—75 Federal Test Procedure (FTP), Supplemental Federal Test
Procedure (SFTP USO6), and an examination of the On—Board Diagnostic II (OBD I1)
system. A 2004 model year Chevrolet €1500 with a 5.3 liter engine (4GMXTO06.0187, LEV 1
SULEV) was used for testing with the SLP PerformancePac installed. Results from
emissions testing conducted at Automobile Club of Southern California, Diamond Bar,
California, are shown below (in grams per mile with deterioration factors applied):

                         CVS—75                              USso6
                  NMOG CO     NOx          HCHO           NMHC+NOx        CO
Standards 50k     0.125 3.4   0.14         0.015          0.40           10.5
With Device       0.084 1.3   0.06         0.001          0.05            0.6

The emission test results in the modified configuration were below the applicable emission
standards. Examination of the OBD II system showed the SLP PerformancePac does not
affect OBD II system operation.

The Air Resources Board 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 THE SLP
PERFORMANCEPAC.

No ciaim 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.
