Pro Circuit logo

Features

  • Pro Circuit’s newest systems offer top-of-the-line performance and power
  • Complete systems from front to back
  • Ti-4 GP systems feature high-quality grade-two aerospace titanium throughout to provide huge weight savings and unique highlights
  • T-4 GP systems feature an aluminum canister and high-grade stainless steel mid-pipe
  • Both are packed with performance features tailored to the demands of serious racers and developed to lower and centralize the machine’s center of gravity, which improves handling and critical clearances
  • In addition to an instant hook-up under power, the systems also offer huge horsepower gains across the rpm range
  • Each model has been rigorously track- and dyno-tested to yield peak performance
  • Inspired by the T-4, the Ti-4 system utilizes high-quality grade-two aerospace titanium to provide huge weight savings and unique highlights
  • Advanced design ensures lightning-quick throttle response and faster, stronger response during hard acceleration
  • CNC-machined modular end-cap design provides tunable power, with effortless reshaping to the machine’s powerband
  • Extensively track- and dyno-tested
  • Silencers include wire-meshed spark arrester that can be removed for closed-course racing
  • Steel Allen head screws make repacking an easy task
  • Exclusive E-glass pillow packing
  • Complete systems come with stainless steel header
  • Can be used with OEM stock or a Pro Circuit header
  • Improved power delivery and exhaust note
  • Body is made from lightweight 6061 T-6 brushed aluminum and the end cap and intake tube are stainless steel
  • Tunable end caps allow fine-tuning of power delivery for different types of riding and terrain
  • Silencers include wire-meshed spark arrester that can be removed for closed-course racing
  • Steel Allen head screws make repacking an easy task
  • Complete systems include stainless steel header
  • Exclusive E-glass pillow packing
  • Revolutionary new system uses a longer aluminum body and special internal E-glass packing to lower noise output to legal dB without sacrificing power
  • Produces an impressive gain in horsepower when compared to OEM
  • Stainless steel intake tube and FIM-approved end cap
  • Completely hand-assembled and -welded for a fit and finish that would rival any Factory Works part
  • Lightweight aluminum mounting brackets
  • Wire-meshed removable spark arrester
  • Modular end caps for tunable power
