For the record i thoroughly approve wholeheartedly with anyone with the cash and the ability to stick a set of fullbore pipes on. You'd be looking at further engine work too though i'd imagine to stop it running like **** although a good powercommander might work with some airbox work.
Did the same with my old zx7r and BOY did it sound mean although not ear-splittingly loud even with the thin-walled race headers. Took about a day fiddling to set up on dyno though.
Anyone remember the gorgeous 916/996 SPS in orange/blue from (i think) Dr Desmo ? It was in a bike mag years ago and stuck in my mind ever since.
and it has the full bad-boy 57mm's too.....
Grrrrrr !!!!!!
