Pro Circuit has revealed new T-6 and Ti-6 exhaust systems for the 2017 KX250F and KX450F which now include improved muffler packing designed to be more heat resistant, keeping the exhaust at optimal performance for as long as possible. 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 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.
