The Pro Circuit Ti-6 Pro Full Titanium Exhaust System is an uncompromising, championship-grade full racing exhaust designed to replace heavy OEM systems with a lightweight, maximum-power competition setup that meets AMA Supercross and Pro Motocross sound regulations. Developed directly in collaboration with the Monster Energy Pro Circuit Kawasaki factory racing team, the Ti-6 Pro is engineered for professional racers seeking every allowable horsepower advantage while strictly complying with the 112 dB AMA/FIM two-meter max sound test.

The entire system—including the precision-stepped header pipe, expansion chamber resonator, mid-pipe, and silencer canister—is hand-welded from aerospace-spec titanium alloy with CNC-machined titanium mounting brackets. The silencer is capped with a lightweight carbon fiber end cap secured by high-tensile hardware. The stepped header design progressively expands exhaust flow diameter to optimize gas scavenging velocity across high-RPM operating zones. Riders experience immediate throttle response, explosive mid-range punch, and exceptional top-end over-rev that pulls smoothly all the way to the rev limiter without premature power drop-off.

  • System Construction: 100% aerospace-grade titanium header, mid-pipe, and canister
  • End Cap: High-durability multi-layer carbon fiber composite
  • Sound Compliance: Engineered specifically to pass strict AMA/FIM 112 dB professional sound tests
  • Header Design: Stepped diameter tube architecture with RC-4 resonance chamber
  • Mounting: Precision TIG-welded CNC titanium mounting brackets

### Step-by-Step Installation & Safety Protocols Installation requires a methodical approach. Remove the factory side panels, silencer, and stock header pipe. Always install a new OEM copper exhaust port gasket in the cylinder head. Fit the Pro Circuit titanium header flange onto the cylinder head studs, keeping the nuts loose. Connect the mid-pipe and silencer assembly, utilizing the provided rubber-cushioned mounting brackets. Check clearances around the rear shock reservoir, swingarm, and water pump hoses. Once aligned perfectly, torque the cylinder head nuts to 14-16 Nm and the chassis mounting bolts to 20-22 Nm. Clean all titanium surfaces with rubbing alcohol before the initial startup to prevent finger oil stains from burning into the metal.

### Maintenance & Service Requirements Maintenance requires repacking the silencer core with Pro Circuit Pillow Packing every 15-25 race hours. Titanium components should be inspected after hard crashes to verify mounting bracket alignment and canister structural integrity.

Frequently Asked Questions

Q: What is the difference between the Pro Circuit Ti-6 Pro and standard Ti-6?

A: The Ti-6 Pro is engineered specifically to meet strict professional AMA and FIM sound regulations (112 dB max sound test) with an unremovable competition core, whereas the standard Ti-6 includes a removable USFS spark arrestor and is tailored for broader amateur closed-course and off-road applications.

Q: Can I run the Ti-6 Pro header with a stock silencer?

A: No. The Ti-6 Pro is designed as a fully integrated, tuned system with specific mating pipe diameters and must be installed as a complete header, mid-pipe, and silencer assembly.

Q: What weight savings does the Ti-6 Pro system provide?

A: Depending on the specific motorcycle model, the full titanium Ti-6 Pro system eliminates approximately 2 to 3.5 pounds of weight compared to stock OEM steel and aluminum exhaust assemblies.

Q: Can I install a spark arrestor in the Ti-6 Pro?

A: No. The Ti-6 Pro features a fixed competition race core designed exclusively for closed-course competition without provisions for an internal spark arrestor screen.
