PRO CIRCUIT Ti-6 System with removable Spark ArrestorTITANIUMSUZUKIRMZ450 18-23Exhaust Description:The T-6 Stainless Steel Exhaust System offers the same benefits as the Ti-6 Titanium Exhaust System, but the T-6 is constructed of stainless steel throughout the head pipe, mid pipe and end-cap while the canister is constructed of aluminum for increased durability and a more affordable alternative to titanium. Although the T-6 will not pass FIM sound requirements seen in professional racing here in the states or in Europe, the T-6 is still a great system for any off-road rider or closed course racer in terms of improved performance, durability and its inexpensive price tag. In addition to all of these features, the T-6 will come with a removable USFS approved spark arrestor making it easy for riders to alternate between off-road and closed course racing.
