                              EXECUTIVE ORDER D—641

                      Relating to Exemptions Under Section 27156
                                 of the California Vehicle Code

                                 Daytona Twin Tec LLC
                                     Twin Tuner EX

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 Twin Tuner EX,
produced and marketed by Daytona Twin Tec LLC of 933 Beville Road, Suite 101H
South Daytona, Florida 32119, 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 2001 to 2008 model year
Harley Davidson motorcycle applications originally equipped with a fuel injected engine
and a 36 pin connector used on the stock Delphi electronic control module.

The Twin Tuner EX is an electronic control module (ECM) that works with the stock
motorcycle‘s ECM and is designed to increase fuel into the combustion chamber during
high load conditions.

This Executive Order is valid provided the installation instructions for the Twin Tuner EX
will not recommend tuning the motorcycle to specifications different from those of the
Daytona Twin Tec LLC.

Changes made to the design or operating conditions of the Twin Tuner EX, 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 Twin Tuner EX using any identification other than that shown in this
Executive Order or marketing of the Twin Tuner EX 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
Twin Tuner EX 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
2008 model year Harley Davidson Softail equipped with a 1.5 liter engine. Test results
showed that emission levels, with the Twin Tuner EX installed and programmed to a
maximum rich setting, met the applicable emission standards when tested using the


Cold—Start CVS—75 Federal Test Procedure (FTP). Results from emissions testing
conducted at Northern California Diagnostic Laboratories, Inc., located in Napa,
California, are shown below in grams per kilometer with deterioration factors applied.

      2008 Harley Davidson 1.5L.
       Softail

       Stds.                                0.6        12
       Device w/ dfs                        0.5          3


Similar effect on motorcycle emissions is expected with the installation of the
Twin Tuner EX on motorcycles listed in this Executive Order.

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
DAYTONA TWIN TEC LLC ‘S TWIN TUNER EX.

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.

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      é‘/}     day of August 2008.
