CRF450R & YZ250F Exhaust

Quality Performance Continues Into 2016 with CRF/YZF Models Below


CORONA, CA - September 25, 2015 - At Pro Circuit, we get just as excited about new models as everyone else and we could hardly wait to get our hands on the new 2016 Honda CRF450R and 2016 Yamaha YZ250F. For '16, the CRF450R will utilize the same T-6 & Ti-6 exhaust systems as the '15 version with the same unmatched performance advantage racers have come to expect from Pro Circuit. The Ti-6 Pro and T-6 Euro systems have been revised for improved performance and still meet the AMA/FIM and European sound requirements. The YZ250F T-6 and Ti-6 systems are all new for 2016 with superior performance gains across the entire RPM range. Additionally, racers with '14-15 YZ250F models also benefit from our endless hours of testing because our new '16 systems also fits these earlier versions as well with the same winning performance.


The Ti-6 Pro Titanium Exhaust System is designed to provide improved performance plus meet the sound requirements for AMA/FIM Pro level competition. Chosen by factory teams and privateers alike for AMA/FIM Supercross and National Motocross racing.

The Ti-6 Titanium Exhaust System is designed for both closed-course and off-road racers. It's the ideal system for AMA Amateur events or any rider or racer looking for winning performance, legendary durability and a professional look. The Pro Circuit Ti-6 System is equipped with a removable USFS approved spark arrestor, making it easy to alternate between off-road and closed-course racing.

The T-6 Stainless Steel Exhaust System is designed for both closed-course and off-road competition. Constructed from high strength stainless steel and aluminum, the T-6 offers the same improved performance as our Ti-6 System. The T-6 System is a great way for riders or racers looking for winning performance, legendary durability and a professional look but at a lower price. In addition, the T-6 System is equipped with a removable USFS approved spark arrestor making it easy to alternate between off-road and closed-course racing.

The T-6 Stainless Steel Slip-On Silencer is for riders looking for an inexpensive, easy-to-install, durable performance silencer that can bolt right onto their stock head pipe. The T-6 Slip-On is constructed of stainless steel and high quality aluminum for increased durability. The T-6 Slip-On is a great option for any rider looking for an increase in performance on a small budget. A removable USFS approved spark arrestor is included to make it easier to alternate between off-road and closed-course racing.

The T-6 Euro System performs like our Ti-6 Pro Titanium Exhaust System except the T-6 Euro is equipped with a stainless steel mid pipe and head pipe to offer riders a lower cost exhaust system that is extremely durable. The T-6 Euro meets the FIM 2-Meter Max sound test, and it is used by our support factory teams in the World MXGP series.
