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. T-4 SLIP-ONS T-4 SYSTEMS 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. T-4R SYSTEMS TI-4 SLIP-ONS 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.) 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.) TI-4 SYSTEMS TI-4R SYSTEMS Some offroad models may contain emission control devices. Some aftermarket parts may remove these devices. Removal or modification of such devices is illegal in the State of California unless used exclusively for closed course competition use ONLY, never to be used on public lands or highways. EXHAUST
