One the best purchases ive made for my cr125.It has great bottom end power which we all know a 125 needs.looks very stylish on my bike very durable no dings so far and matches with my pro ciruit silencer perfect best combo exhaust system for a 125 ive found
One of the best upgrades you can make for a 2 stroke. Quality materials and craftmanship. Perfect fit. Produces excelent power from mid to top. Had to rejet and adjust the power valve a little but once it hits its sweet spot hold on.
Had issues getting our KTM SX 250 stroker to rev past 8000 RPM, it would hit 8000 RPM and just drop off. The builder suggested trying a different pipe. Bolted on the Pro Circuit and the problem was solved. The bike would rev well over 10000 RPM and beyond and picked up 2.5 hp. This is a great pipe and we highly recommend it.
