I rode the Pro Circuit on a lot of different style trails. It gives more torque and harder hit. It’s like it chokes up the engine low-mid (leaned out the pilot and needle diameter, as well as get the needle taper lower) and when the power valve opens it puts a nice smile on your face. So far, it feels more playful and definitely sounds better.
The only downside is that it is a large pipe and is close to the radiators brand new.
