how come there's no EGR valves, air pumps, catalytic converters, upshift delay on these ?
does Pagani Zonda have to prove it's worth more power, taking them off ?
do they have to post "before/after" track times ?
no. they just don't put them on in the first place. ask yourself why.
because it's understood. you don't need no emissions controls.
