CALIFORNIA EXHAUST NOISE TESTING PROGRAM PROVES OVERWHELMING
SUCCESS
Nine of Ten Vehicles Tested by BAR Are in Compliance with California Law

WASHINGTON (Jan. 14, 2004) -- The California Bureau of Automotive Repair (BAR)
reports that approximately 90 percent of the nearly-600 vehicles that have undergone the
state's new exhaust-noise test have been certified to be in compliance with California
law. BAR began operation of the motor vehicle exhaust noise-testing program in late
summer 2003. The program, the product of a SEMA-sponsored law, allows California
hobbyists to prove their vehicles comply with state noise standards.

"This information validates our long-held contention that a vast majority of citations
written for violation of California's exhaust noise laws are, in fact, erroneous," said SEMA
Senior Director of Government Affairs Steve McDonald. "For years, the enforcement
policy used by police officers has deemed nearly all exhaust system modifications illegal,
even when the noise levels met state standards."

The law also allows courts to dismiss citations for exhaust systems that have been tested
and for which a certificate of compliance has been issued. The 40 Smog Check stations
that provide referee functions are performing the test. These referee stations are issuing
certificates of compliance for vehicles when tests of their exhaust systems demonstrate
that they emit no more than 95decibels under SAE test procedure J1169. However, only
those vehicles that have received a citation for an exhaust noise violation are permitted
to submit their vehicle for the test.

"Motorists who modify their vehicles for durability, appearance and performance prefer
aftermarket exhaust systems," McDonald added. "By establishing this evenhanded
testing process, this program is proving to benefit consumers who favor these state-of-
the-art products, the aftermarket industry which markets them and even police officers
who are charged with enforcing the law."

BAR has yet to issue a regulation to provide for the cost to consumers for performing the
test. Tests are currently being performed at no cost to consumers. BAR has established a
toll free number (800/622-7733) to accept phone calls from motorists who have received
citations for excessive exhaust noise and wish to have the test performed. BAR officials
have asked that cited motorists have the citation and vehicle registration information
available when calling.

In Pennsylvania they have established decible maximums for exhaust, what they failed to do though, Was supply the police with an instrument to measure the decibles :D
The two major cities (Pittsburgh & Philly) have meters, but they generally use them for loud stereos.
We have no problems with the exhaust Cops ;)

its not about smog. exhausts dont clean shit anyways... its about how loud your exhaust is... but 95dbs? what quality exhaust system (greddy, hks, tanabe, dc, apexi, etc...) cant beat that?
