L INTRODUCTION

              Pacesetter Marketing, Inc. of 4433 West Van Buren #3, Phoenix, Arizona 85043 has applied

for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for their

Shorty Headers designed for 1988—97 5.71 and 1996/97 4.3L General Motors trucks.

IL CONCLUSIONS

              Based on submitted emissions test data of the Shorty Headers, the staff concludes that

Pacesetter Marketing, Inc.‘s Shorty Headers will not adversely affect exhaust emissions from the vehicles

for which the exemptionis requested.

III. RECOMMENDATION

              The staff recommends that Pacesetter Marketing, Inc. be granted an exemption for their

Shorty Headers for installation on those applicable vehicles. The staff also recommends that Executive

Order D—439 be issued.

IV. HEADERS

             The Shorty Headers are designed for installation on 1988—97 5.7L and 1996/97 4.3L General

Motors trucks. The purpose of the device is to increase the vehicle‘s performance and power output by

allowing more air to flow out of the engine‘s combustion chamber with less restrictions.

             The original exhaust manifold is a one piece cast iron manifold with variable port and

chamber diameters. The manufacturer claims the tube diameter of the header is constant with no

bottlenecks to create back pressure; thereby enhancing exhaust flow. All other characteristics of the OEM

manifold are similar including the mounting to the stock connecting pipes. The header operates in

conjunction with the OEM emission control systems already certified with the stock engine. The Shorty

Headers do not defeat any emission control devices required by the manufacturer nor does it alter or

circumvent the vehicle‘s On—Board Diagnostic II system or tune—up specifications.


v.             THE

               A 1996 Chevrolet C1500 truck with a 5.7 liter engine was used for the evaluation of the

header. The dynamometer inertia weight and loading were 5500 Ibs, and 14.2 hp. respectively. Emissions

testing was conducted by Northern California Diagnostic Laboratory (NCDL), Napa, California.

               Emissions testing conducted by NCDL consisted of one Cold—Start CVS—75 Federal Test

Procedure in the modified (Shorty Headers installed) configuration. The Air Resources Board did not

perform tests to confirm the test results submitted by the applicant. A summary ofthe test results is shown

below:

                                        Exhaust Emissions Test Results
                                        —OmaA997—Chorrolet—Camuse

Mode                            NMHC                     _CO                     NQOx

Standard                         0.32                      4.4                      0.7
Device     w/ dfs                0.20                      3.0                      0.4

               Results from the emission tests conducted at NCDL show the vehicle emissions with the

Shorty Headers installed with deterioration factors applied to be withim the vehicle‘s emission standards.

Based on the test results, the staff concludes that the installation of the Pacesetter Marketing, Inc.‘s Shorty

Headers will not have an adverse effect on exhaust emissions ofthe affected vehicles.

              The evaluation ofthe Shorty Headers on the vehicle‘s OBD II system was conducted by

NCDL. NCDL indicated that a scan test displayed the vehicle‘s readiness monitors as complete and that

no diagnostic trouble code were present.. An ARB staff from In—use Compliance witnessed the OBD II test

at NCDL.

               Pacesetter Marketing, Inc. has submitted all the required information and fulfilled the

requirements for an exemption.
