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.

The T-4R has the same performance and features as
the Ti-4R except the only difference is the aluminum
canister, stainless steel head pipe, mid pipe and end-
cap. The T-4R offers unparalleled performance at a
price that will fit into most rider’s budgets.
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.

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. (Depending on the year of
your bike, the RC-4 Resonance Chamber may or may
not come with your system.)
