Hello, I have a question about the Wood 22EX..seems you all have some good experience with..question: on a late model touring with Cobra 909's, and a modest air intake and Power Vision tune, what differences could we expect in torque curve and hp curve shape if we keep the original headers (with cats)and narrow band o2 sensors, as opposed to no cats in place? I'm evaluting the need to replace the headers when installing my 22XE..for the record,i have a catless duel exhaust with a Se-447 on my other m8 touring bike with Power Vision custom tune..thanks
