I was talking this topic with some of my friends last night, one of my buddy said his B16A1 VTEC is louder, another one said his H22 VTEC is louder, ane I said my GS-R VTEC is loud as ****, which one you think its right? I've droven both of their's car, but IMO, my GS-R VTEC is lounder then both ot their's B16A1 and H22, GS-R has dual stage VTEC..
