I was pretty sure that the VTEC engagement point on the F22b1 is 3200rpms, can someone else confirm this? The only other thing I have done to the car is an intake, and I can vouch for the quality of RSR, a guy gave this exhaust to me for free, he used to tune his Accord, so I am assuming he had it before RSR left the USA a couple years back. It fit perfectly when I bolted it in, and it all feels sturdy even tho its used.
