Pro Circuit T-4 Complete Exhaust System - Features
The Pro Circuit T-4 system is an aluminum and stainless replica of our more-exotic titanium Ti-4 exhaust. Although the T-4Gis slightly heavier than the Ti-4, it still offers a considerable weight savings when compared to the OEM exhaust system. This exhaust system is ideal for a racer on a budget that is not willing to compromise on performance! The only difference between the T-4 and Ti-4 is that high-quality stainless steel replaces the Ti- 4 titanium. The T-4 comes complete with our stainless head pipe that works in conjunction with the silencer to produce more power from bottom to top. The use of stainless steel for the header pipe offers increased strength and should give years of trouble-free use. The silencer canister is easy to repack by removing the inlet cap screws and re-wrapping the silencer core. The T-4 meets all AMA sound restrictions.
