If you are looking for an inexpensive, easy-
to-install, lightweight performance silencer
we have just what you need. Our T-4 Slip-On
Silencers (a.k.a. T-4S) offer all that and more.
T-4 Slip-Ons are a perfect alternative for those
people who do not need or want to replace
their stock head pipe. Each T-4 Slip-On comes
with the aluminum silencer and stainless mid
pipe and can be bolted onto your bike in a
matter of minutes! (2008 and earlier models
may vary in design, price and accessories that
are included. Call for information.)
The T-4 System is a tunable version of our
more exotic Ti-4R System. RC-4 Resonance
Chamber has been added to the head pipe to
reduce noise. (The RC-4 Resonance Chamber,
depending on year of your bike, might not
come with the system.) Please contact Pro
Circuit for information on replacement parts.

If you’re looking for increased performance
there is no faster, or less expensive, way to get
it than a Pro Circuit Slip-On Silencer. These
silencers will bolt onto the stock or Pro Circuit
head pipes in a matter of minutes. In addition
to the extra power, the Ti-4 Slip-On Silencers
are substantially lighter and are designed to
be easily re-packed to keep performance at its
peak.

Designed as a “full race” system, the Ti-4
Titanium Exhaust System will boost power
from the bottom to the top and offers incredible
weight savings when compared to the stock
exhaust. The Ti-4 includes a United States
Forest Service (USFS) Approved Spark
Arrestor. (2008 and earlier models may vary
in design, price and accessories that are
included. Call for information.)Ti-4 Slip-Ons
The Ti-4R Titanium Exhaust System was
designed specifically to deliver unparalleled
performance for closed course competition.
