     The Bassani Manufacturing Equal Length Exhaust Manifold Assembly includes

exhaust manifolds which are designed to replace the original equipment

manufacturer exhaust manifolds and provide for the connection of all emission

control devices.     The installation of the Bassani Manufacturing Equal Length

Exhaust Manifold Assembly does not require any adjustments or modifications to

the emission control systems of the applicable vehicles.

       Based on the results from emission tests performed at an independent

 laboratory on a 1995 5.8 liter Ford F150 light duty truck, the staff concludes

— that Bassani Manufacturing‘s Equal Length Exhaust Manifold Assembly will not


adversely affect exhaust emissions from vehicles for which an exemption is

requested.

       The staff recommends that Bassani Manufacturing be granted an exemption

as requested and that Executive Order D—374 be issued.

III.      RECOMMENDATION

       The staff recommends that Bassani fianufacturing be granted an exemption

for their Equal Length Exhaust Manifold Assembly for installation on those

vehicles listed above.     The staff also recommends that Executive Order D—374 be

issued.

Iv.       DESCRIPTION OF THE BASSANI MANUFACTURING EQUAL LENGTH EXHAUST MANIFOLD

          ASSEMBLY

       The Bassani Manufacturing Equal Length Exhaust Manifold Assembly is

designed for installation on the vehicles listed above. The Equal Length

Exhaust Manifold Assembly operates in conjunction with the original equipment

manufacturer‘s (OEM)‘computer controlled fuel injection system and emission

control systems.

       The purpose of modifying the exhaust system of the engine is to increase

the efficiency of exhaust gas scavenging which results in increased performance

and fuel economy.     As with the OEM exhaust system, Bassani Manufacturing‘s

Equal Length Exhaust Manifold Assembly, routes exhaust gases from the engine to

the OEM head pipes.     The Equal Length Exhaust Manifold Assembly includes equal~

length, "shorty" style headers that bolt—in without modification to the OEM

head pipes.

       The headers have a 4—into—1 configuration with four equal length primary

tubes merged into a single collector.     Part numbers 50150 and 58150 consist of

primary tubes of 1.5 inch diameter, 0.075 inch wall thickness,    1008 ASTMS13

carbon steel.    Part ;umbers 5093 and 5094 consist of primary tubes of 1.625

inch diameter, 0.075 inch wall thickness, 1008 ASTMS13 carbon steel.     Part

numbers 581508 and 58150L consist of stepped primary tubes of 1.5 and 1.625

inch diameter, 0.075 inch wall thickness, 1008 ASTMS13 carbon steel.     Part

numbers 58150L—1 consists of primary tubes of 1.625 inch diameter, 0.075 inch

wall thickness, 1008 ASTMS13 carbon steel.     The Bassani Manufacturing Equal

                        1988—95     Ford Bronco                  5.8 liter

      Bassani Manufacturing has submitted test data from a 1995 Ford F150 light

duty truck equipped with a 5.8 liter engine which was tested at California

Environmental Engineering (CEE), Santa Ana, California.

II.     CONCLUSION

      Based on the fesults from emission testing performed at CEE on a 1995 Ford

F150 light duty truck, the staff concludes that Bassani Manufacturing‘s Equal

Lengtfi Exhaust Manifold Assembly will not adversely affect exhaust emissions

from vehicles for which an exemption is requested.


Length Exhaust Manifold Assembly uses individual port flanges for each primary.

The four primaries are welded into a coilectcr formed from 3 inch diameter,

0.,.090 wall thickness steel tubing.   The collector outlet diameter on all

headers is 2 inches.     The collector outlet is a duplicate of the factory ball—

and—socket type utilizing fixed studs to ensure a no leak connection and

complete interéhangeability with the OEM exhaust.     The standard finish on all

headers is industrial chrome.     Plasma aluminum spray coating and HPC high

temperature coating are available as options to the chrome finish.

     Installation of Bassani Manufacturing‘s Equal Length Exhaust Manifold

Assembly does not alter the OEM location of the oxygen sensor and the catalyst.

The tune—up specifications are also unaltered from the OEM tune—up

specifications.     All brackets, gaskets, hardware, and instructions are included

with the header kits.

v.       DISCUSSION_OF THE BASSANI MANUFACTURING EQUAL LENGTH EXHAUST MANIFOLD

         ASSEMBLY

     A 1995 Ford F150 truck equipped with a 5.8 liter gasoline engine certified

to Tier 1 standards was used for the evaluation of the Equal Length Exhaust

Manifold Assembly.     The emission tests conducted by CEE consisted of three Cold

Start CVS—75 Federal Test Procedures (FTP‘s) with the Equal Length Exhaust

Manifold Assembly, part number 581505, installed.

     The Ford F150 was chosen as the most popular/worst case vehicle/engine

application.    The estimated test weight and horsepower setting were 5250 pounds

and 15.4 horsepower respectively.      The emission tests conducted by CEE for

Bassani Manufacturing consisted of three cold start FTP‘s in the modified

(Equal Length Exhaust Manifold Assembly installed) configuration.      The test

vehicle procured by CEE did not have the required minimum of 4,000 accumulated

miles.    CEE intended to demonstrate emission stability by testing at 2592 miles


{Test 1)   and 3194 miles (Test 2).   Test 1 was conducted immediately after the

Equal Length Exhaust Manifold Assembly Qaa installed.      As a result, CEE clainms

the emissions were unstable because there was insufficient time for the

vehicle‘s adaptive learn to adjust to the headers.       As such the data from Test

1 were not used for the evaluation of the headers.       A third test, Test 3, was

conducted to back up the data from Test 2.     The ARB did not perform any tests

to confirm the test results submitted by the applicant.      A summary of the test

results is shown below:

  Test 2 (3194 miles)             0.136         0.862         0.211
  Test 3 (3245 miles)             0.120         0.732         0.206

  Average with DF applied       0.165           0.934         0.209
  50k Standard                     0.32         4.4           0.7


     Test 2 and Test 3 were averaged and the 50,000 mile DF was applied to the

average.     The average results from the emission tests show the vehicle

emissions with the Bassani Manufacturing Equal Length‘Exhaust Manifold Assembly

installed did not exceed the test vehicle‘s "California Exhaust Emission

Standard."     Therefore, based on the test results, the staff concludes that the

installation of Bassani Manufacturing‘s Equal Length Exhaust Manifold Assembly

will not have an adverse effect on exhaust emissions on the vehicles for which

exemption is requested.

     Bassani Manufacturing has submitted all the required information and

fulfilled the requirements for an exemption.
