Not sure about pro circuit but not heard good things about the yoshi pipe apart from its looks. I wish magazines would dyno bikes with each manufacturerd exhaust to see comparisons. Probably too many politics involved
Yea cause I’ve got the 2022 crf450r and I’m thinking of getting the yoshi titanium for 2,300 but idk I want the fmf but they don’t make a fmf exhaust only pipe
