Is loudness an issue for you?

not really.

 

The HMF, White Bros R4, and Pro Circuit T4, are all favorites around here... However, they are VERY loud. They also deliver the most flow and that is what you need to bring that 660 alive. None of them will void your warranty. You will also need a K&N filter and to rejet. I recommend putting a pro-flow kit on to adapt your airbox to a clamp-on filter system. It's much safer for your engine.

Ditto!!

HMF, Airbox lid removed and rejet to Mikuni 180 Main.

She'll rip a ton harder than a stocker. Want a boatload more torque, get a Wiseco 11:1 piston.

Now, if SOMEBODY would develop a damm new ignition we'd have Raptor like power.

 

grizzlys are friggin beasts, why do u need more power they got lots of hp and tons of torque
