Has anyone had experience with a proper airbox for itb’s like the reverie zolder? I’m looking to quite down the front end and have plenty of space to make a airbox fit but being n/a concerned about loosing horses.    Reading up seems very conflicting advice with manufactures saying it’ll increase Bhp where others suggesting the opposite. Has anyone gone down this route? I’d love to visit some of the quieter tracks but ultimately don’t want to spend a fortune to undo some of the extra power the bodies give in the first place
