                                  EXECUTIVE ORDER D—374—4

                          Relating to Exemptions Under Section 27156
                                       of the Vehicle Code

              Exhaust Header System, Part Nos. 572324, 572324C, and 830000C

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 Exhaust Header System,
manufactured and marketed by Bassani Manufacturing, 2900 E. La Jolla, Anaheim, California,
92806 has been found not to reduce the effectiveness of the applicable vehicle poliution control
system and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for
2003 through 2005 model—year Chrysler Trucks equipped with a 5.7L engine, and 2004 to 2005
model—year Chrysler Trucks equipped with an 8.3L engine.

The Exhaust Header System is a pair of shorty length exhaust headers, manufactured out of
14 gage mild steel. Part numbers 572324 and 5723240 are designed for 2003 through 2005
model—year Chrysler Trucks equipped with a 5.7L engine. A new 12 inch connecting pipe is
included with the 5.7L headers that will be welded to the catalytic converter. The oxygen
sensor is installed in the new 12 inch connecting pipe, similar to stock. Part no. 830000C is
applicable to 2004 to 2005 model—year Chrysler Trucks equipped with an 8.3L engine. The
8.3L headers are direct replacements and do not require any modifications to the stock
connecting pipes.

Executive Order is valid provided that the installation instructions for the headers 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 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.

This Executive Order shall not apply to any Bassani Manufacturing‘s Exhaust Header System
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 headers using any identification other than that shown in this Executive Order
or marketing of the 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 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 headers
may have on any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on emissions test data generated on a 2004 model year
Dodge Ramh equipped with a 5.7L engine and certified to the Super Ultra Low Emission Vehicle
(SULEV) emission standards. Emission levels of the modified vehicle met the applicable
emission standards over the Cold—Start CVS—75 Federal Test Procedure (FTP) and the
Supplemental Federal Test Procedure (USO6) test cycles. Results are in grams per mile with
deterioration factors added to CVS—75 FTP results:

Standards         0.125 3.4      0.14    0.015              0.40         10.5

This Executive Order is also based on an On Board Diagnostic II (OBD II) testing which showed
that the Exhaust Header System when installed on the vehicle did not affect the vehicle‘s ability to
perform its OBD 11 monitoring.

to the action taken herein in any advertising or other oral or written communication.
