The Performance Baffle Kits, part numbers 1548, 1550, 1551 and 1552, are exhaust
muffler baffles designed to replace the stock Harley Davidson baffles located inside the
stock muffler. Installation is conducted by Cycle Shack only and does not allow any
modifications to or removal of the stock catalyst located inside the stock muffler.

This Executive Order is valid provided the installation instructions for the Performance
Baffle Kits will not recommend tuning the vehicle to specifications different from those of
the vehicle manufacturer.

Changes made to the design or operating conditions of the Performance Baffle Kits, as
exempt by the Air Resources Board, which adversely affect the performance of the
vehicle‘s pollution control system shall invalidate this Executive Order.

for sale, sold with, or installed on a new motor vehicle prior to or concurrent with transfer
to an ultimate purchaser.

in this Executive Order or marketing of the Performance Baffle Kits for an application
other than those listed in this Executive Order shall be prohibited unless prior approval
is obtained from the Air Resources Board.


This Executive Order does not constitute any opinion as to the effect the use of the
Performance Baffle Kits may have on any warranty either expressed or implied by the
vehicle manufacturer.

This Executive Order is granted based on previously submitted emission test data
generated on a 2008 model year 1.6L Harley Davidson Touring motorcycle modified
with the Performance Baffle Kit. Test results showed that emission levels, met the
applicable emission standards when tested using the Cold—Start CVS—75 Federal Test
Procedure (FTP) test. Results from emission testing conducted at Northern California
Diagnostic Laboratories, Inc., located in Napa, California, are shown below, with
deterioration factors (df) applied to CVS—75 FTP results.
