CATALYTIC CONVERTER REMOVAL PLATE
FOR YAMAHA
GP1200R/GP13OOR,XLL/XLT1200
This plate allows you to remove the catalytic converter easily and fills the gap
where the catalytic converter mounts on the OEM exhaust system. Benefits
include a cooler running exhaust system and ability to run any kinds of two-
stroke oil. The plate features a centrally located outlet designed to give some
beneficial back pressure but with much better exhaust gas flow compared to an
offset or cutout plate. This gives better response and acceleration throughout
the power band.

R&D is now producing the new Sound Suppression Removal Tube for the GPR. This
modification allows the exhaust to free flow out of the water box adding bottom end
punch and overall performance. Replacing of the stock plastic sound box with the
R&D Sound Tube will eliminate potential melting failures in limited and superstock
modified applications. Easily installs, no cutting of hoses necessary.
