                     .      EXECUTIVE ORDER D—324
                   Relating to Exemptions Under Section 27156
                             of the Vehicle Code

                    EXTRUDE HONE ABRASIVE FLOW MACHINING
                 EXTRUDE HONE ABRASIVE FLOW MACHINING PROCESS

Pursuant to the authority vested in the Air Resources Board (ARB) by Section
27156 of the Vehicle Code; and

Pursuant to the authority vestéd in the undersigned by Sections 39515 and
39516 of the Health and Safety Code and Executive Order G—45—5;

IT IS ORDERED AND RESOLVED:  That the application of the Extrude Hone
Abrasive Flow Machining Process, performed by Extrude Hone Abrasive Flow
Machining, has been found not to reduce the effectiveness of required motor
vehicle pollution control devices and, therefore,    is exempt from the
prohibitions of Section 27156 of the Vehicle Code for exhaust manifolds,
intake manifolds, and cylinder heads from 1993 and earlier model year
vehicles equipped with gasoline engines.

No more that 0.035 inches of material may be removed from any surface when
the Extrude Hone Abrasive Flow Machining Process is used.

This Executive Order is valid provided that instructions for the Extrude
Hone Abrasive Flow Machining Process will not recommend tuning the vehicle
to specifications different from those submitted by the device manufacturer.

Changes made to the process, as exempted by the ARB, that adversely affect
the performance of a vehicle‘s pollution control system shall invalidate
this Executiye Order.

Marketing of this process using an identification other than that shown in
this Executive Order or marketing of this process for an application other
than those listed in this Executive Order shall be prohibited unless prior
approval is obtained from the ARB.

This Executive Order does not constitute any opinion as to the effect A
that this process may have on any warranty either expressed or implied by
the vehicle manufacturer.

This Executive Order is granted based on results from emissions tests
conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
However, the ARB finds that reasonable grounds exist to believe that the
Extrude Hone Abrasive Flow Machining Process may adversely affects 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 Extrude Hone Abrasive


 EXTRUDE HONE ABRASIVE FLOW MACHINING                      EXECUTIVE ORDER D—324
 EXTRUDE HONE ABRASIVE FLOW MACHINING PROCESS                       (Page 2 of 2)

 Flow Machining Process 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 Extrude Hone Abrasive Flow Machining Process will affect
the durability of the emission control system, Extrude Hone Abrasive Flow
Machining 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 Reqgulations, 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 EXTRUDE HONE ABRASIVE FLOW MACHINING‘S EXTRUDE HONE ABRASIVE
FLOW MACHINING PROCESS.

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.

Section 17500 of the Business and Professions Code makes untrue or
misleading advertising unlawful, and Section 17534 makes violation
punishable as a misdemeanor.

Section 43644 of the Health and Safety Code provides as follows:

       "43644,   (a)   No person shall install,      sell,   offer for sale,      or
       advertise, or, except in an application to the state board for
       certification of a device,   represent,     any device as a motor vehicle
       pollution control device for use on any used motor vehicle unless that
       device has been certified by the state board.  No person shall sell,
       offer for sale, advertise, or represent any motor vehicle pollution
       control device as a certified device which,         in fact,   is not a certified
       device.   Any violation of this subdivision is a misdemeanor."

Any apparent violation of the conditions of this Executive Order may result
in its rescission or submission to the Attorney General of California for
such action as he deems advisable.
