Vehicle Code; and

Pursuant to the authority vested in the undersigned by Section 3951 5 and Section 39516 of
the Health and Safety Code and Executive Order G-45-9;

IT IS ORDERED AND RESOLVED: That the installation of the Tubular Exhaust System,
manufactured and marketed by the Toyota Racing Development, 1382 Valencia Avenue,
Tustin, California 92780 has been found not to reduce the effectiveness of the applicable
vehicle pollution control system and, therefore, is exempt from the prohibitions of Section
271 56 of the Vehicle Code for the vehicle applications listed:

Part No.                    Application
00602-17141-01 0            1999-2001 4.7L Landcruiser, LX470, and Tundra
00642-17141-01 3            1983-1995 2.2L/2.4L SR5 truck, 1984-1987 2.2L/2.4L 4Runner
00642-17141-014             1983-1995 2.2L/2.4L SR5 truck, 1984-1987 2.2L/2.4L 4Runner

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

The Tubular Exhaust System, part no. 00602-17141-010, is a long tube header
manufactured out of a 1 1/2 inch outside diameter (o.d.), 16 gage stainless steel tubing. Part
nos. 00642-17141-013 and 00642-17141-014 are long tube headers manufactured out of a
1 3/8 inch o.d., 16 gage mild steel tubing with a ceramic coating. The location of the
oxygen sensor is moved downstream on part no. 00602-17141-010 only, a wire extension is
supplied for the right hand side oxygen sensor.

Changes made to the design or operating conditions of the Tubular Exhaust 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.

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


This Executive Order is granted based on the emissions test data on two vehicles certified
to the Low Emission Vehicle (LEV) emission standards:

                   1999 4Runner, 3.41                          2001 Tundra, 4.7L

                   NMOG CO        NOX     HCHO                 NMOG CO         NOX HCHO
Standard          0.100 4.4       0.4     0.018                0.160 4.4       0.4 0.018
Device w/ dfs     0.059 0.6       0.2     0.003                0.134 1.1       0.2 0.001

Test results showed that tailpipe emissions with the Tubular Exhaust System installed on
the vehicles met the applicable emission standards during a Cold Start CVS-75 Federal
Test Procedure. This Executive Order is also based on.the On Board Diagnostic II (OBD 11)
testing conducted on the same test vehicles. Test data showed that the Tubular Exhaust
System when installed on the vehicles did not affect the vehicle's ability to perform its OBD
II monitoring.
