                                        EXHAUST HEADERS, P/N LCHSO57


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 Exhaust Headers, manufactured and marketed by La
Pole Custom Headers, 8 Calle Coturno, Rancho Santa Margarita, California 92688—2308 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 1987 to 1995 General Motor trucks equipped with either a 5.0 or 5.7L engine.

The Exhaust Headers are a short tube style header manufactured out of 16 gage mild steel tubing. The location of the
oxygen sensor is located in the collector of the header. Connecting pipes manufactured out of 16 gage mild steel are
included.

This Executive Order is valid provided that the installation instructions for the Exhaust Headers will not recommend
tuning the vehicle to specifications different from those of the vehicle manufacturer.

This Executive Order shall not apply to any La Pole Exhaust Header 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 Exhaust Headers, 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 Exhaust Headers using any identification other than that shown in this Executive Order or marketing
of the Exhaust Headers 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 Exhaust Headers 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 Exhaust Headers 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 1994 General Motors 5.7L
C1500 truck:
                    NMHC CO            NOx
Baseline            0.29       4.3     1.3
La Pole Headers       0.28      4.0     1.3

Test results showed that tailpipe emissions with the Exhaust Headers installed on the vehicle did not cause exhaust
emissions to exceed the baseline emissions by more than the allowed limits of 10 percent or 0.1 grams per mile on
hydrocarbon (HC) and oxides of nitrogen (NOx), and 15 percent or 1.0 grams per mile carbon monoxide (CO) as
specified in the "Procedures for Exemption of Add—On and Modified Parts".

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
