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—14—012;

IT IS ORDERED AND RESOLVED: That the installation of the Shorty Headers,
manufactured and marketed by Holley Performance Products, 1801 Russellville Road,
Bowling Green, Kentucky 42101, 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 following vehicle applications
listed in Exhibit A:

The Shorty Headers, are a pair of shorty style headers, manufactured out of 16 gage
mild steel with either a painted or ceramic finish. The oxygen sensor is retained in the
stock location, at a collector. The headers bolt to the vehicle‘s stock connecting pipe.

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

Changes made to the design or operating conditions of the Shorty 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 Shorty Headers using any identification other than that shown in this
Executive Order or marketing of the Shorty 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.

This Executive Order is granted based on submitted emission test data generated on
one test vehicle modified with a pair of Shorty Headers. Test results showed that
emission levels, with the Shorty Headers installed, met the applicable emission


 applicable emission standards when tested using the Cold—Start CVS—75 Federal Test
 Procedure (FTP) test cycle and the Supplemental Federal Test Procedure (SFTP
 USO6/SC03) test cycle. Examination of the OBD II system showed that the Shorty
 Headers did not affect OBD II system operation. Results from emissions testing
 conducted at SEMA Garage, Diamond Bar, California, are shown below, in grams per
 mile, with deterioration factors (df) applied.
