Exhaust Header System                                          (Page 2 of 3)

The Exhaust Header System is manufactured out of 14 gage stainless steel. Connecting
pipes are included. The oxygen sensor is located at the header collector.

This Executive Order is valid provided the installation instructions for the Exhaust Header
System will not recommend tuning the vehicle to specifications different from those of the
vehicle manufacturer.

This Executive Order shall not apply to any Exhaust Header System advertised, offered for
sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

Changes made to the design or operating conditions of the Exhaust Header System, 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 Exhaust Header System using any identification other than that shown in
this Executive Order or marketing of the Exhaust Header System 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 Exhaust Header System 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 Exhaust
Header System may have on any warranty either expressed or implied by the vehicle

This Executive Order is granted based on emissions test data generated on a 2000 Pontiac
3.8L Grand Prix, certified to the Low Emission Vehicle (LEV) emission standards. Testing
consisted of a Cold Start CVS—75 Federal Test Procedure. Emission levels of the modified
vehicles were either at or below their applicable emission standards. The following test
results are in grams per mile:

                2000 Pontiac 3.8L Grand Prix

                   NMOG           CO        NOx     HCHO
Standards          0.075          3.4       0.2     0.015
Device w/ dfs      0.061          0.9       0.18     0.001

This Executive Order is also based on the On Board Diagnostic II (OBD II) testing conducted
on a 2000 General Motors 5.3L Suburban. Test data showed that the Exhaust Header
System when installed on the vehicle did not affect the vehicle‘s ability to perform OBD II
