                              EXECUTIVE ORDER D-176-33

                       Relating to Exemptions Under Section 271 56
                                  of the California Vehicle Code

                                Dinan Engineering, Inc.
       High Flow Throttle Body and High Flow Throttle Bodies and Velocity Stacks

Pursuant to the authority vested in the Air Resources Board by Section 271 56 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 High Flow Throttle Body
and High Flow Throttle Bodies and Velocity Stacks, produced and marketed by Dinan
Engineering, Inc. of 865 Jarvis Drive, Morgan Hill, Califorr~ia95037, 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
2000 through 2006 model year BMW vehicles as listed in Exhibit A, excluding the 2003 to
2006 model year BMW vehicles with engine test groups 3BMXV02.5M56,
4BMXV02.5M56, 5BMXV02.5M56, or 6BMXV02.5M56 which have been certified to a
Low Emission Vehicle II Super Ultra Low Emission Vehicle (LEV II SULEV) emission
standards.

The High Flow Throttle Body includes a modified throttle body with a larger diameter for
increased air flow. The High Flow Throttle Bodies and Velocity Stacks are a set of eight
throttle bodies and velocity stacks located in the intake plenum chamber of the 2000 to
2003 model year 4.9L V8 BMW 28 and M5. The High Flow Throttle Bodies and Velocity
Stacks are both modified with a larger inner diameter, the velocity stack is also slightly
shorter than the stock velocity stack. No other modifications are required for installation
other than the replacement of the stock unit with Dinan's unit.

This Executive Order is valid provided that the installation instructions for the High Flow
Throttle Body and High Flow Throttle Bodies and Velocity Stacks 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 High Flow Throttle Body and
High Flow Throttle Bodies and Velocity Stacks, 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 High Flow Throttle Body and High Flow
Throttle Bodies and Velocity Stacks 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 High Flow Throttle Body and High Flow Throttle Bodies and Velocity
Stacks using any identification other than that shown in this Executive Order or marketing
of the High Flow Throttle Body and High Flow Throttle Bodies and Velocity Stacks 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 High
Flow Throttle Body and High Flow Throttle Bodies and Velocity Stacks nits may have on
any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on submitted emission test data generated on a
2006 model year BMW 3251, engine test group 6BMXV03.ON52, certified to the Low
Emission Vehicle II Llltra Low Emission Vehicle (LEV II LILEV) emission standards. Test
results on the BMW 3251 showed that emission levels, with Dinan Engineering, Inc.'s High
Flow Throttle Body installed, met the applicable emission standards when tested using
:lie Cold-Start CVS-75 Federal Test Procedure (F-TP) and the Supplemental Federal Test
Procedure (SFTP US06) test cycles. Examination of the OBD II system showed the High
Flow Throttle Body did not affect OBD II system operation. Results from emission testing
conducted at Automotive Testing and Development Services, Inc., located in Ontario,
California are listed below with deterioration factors applied.
