Full Exhaust Pro Circuit for 4-stroke engines. There are different models, all have similar output and power, but different weights due to different materials: Ti-6 Pro, Ti-6 and T-6.

• Power increase over the entire rpm range without modifying engine characteristics
• Ti-6 made of titanium with carbon end cap for minimum weight
• T-6 made of stainless steel with silencer end cap either made of carbon or impact-resistant aluminium
• Ti-6 Pro similar to Ti-6, but meets AMA and FIM noise standards
• Ti-6 / T-6 will pass AMA amateur noise requirements but not FIM sound requirements for professional racing
• Ti-6 and T-6 with removable United States Forest Service (USFS) approved spark arrestor
• Silencer bracket machined from aluminum
• Most manifolds are equipped with an RC-4 resonance chamber to reduce noise
• Milled flange for optimal fit
