arrow vs qd quad box

[2mheelsnuts]

Taking in consideration that the bike is a 2007 s4rs. Performance wise is there a comparison (dyno chart) between the full arrow exhaust and the QD quad box?

A conventional exhaust will make more power than the QD - especially on a S4RS. The QD ex-box usually makes less power than a slip-on exhaust.

thanks for the info. I think I will go full arrow then.

Has anyone got numbers for the QD Exbox on a 1100 monster? I have heard they don't do well.
