> airfilters and change the downpipes and box to a Thunder Ace downpipes / box > , as the standard pipes are to small diameter wise . > I did the above to mine and it went from 92 hp to 106
>When you say you changed the box, do you mean the air box or just the >filters. Using the YZF downpipes did you keep the stock convertor? >Bob Hi Bob , i removed the whole airbox ( i cable tied the air sensor that was in the airbox to the throttle bodies ). The catalytic converter is removed , the down pipes and collector box come as one piece ( their is an EXUP valve in the collector box ) i removed the valve and welded a plate over the hole , i cut the lambda sensor "thread" off the old collector box and rewelded it on to the new one , i had to alter the outlet from the collector box to the end can , to get the can /box to line up . As far as i can remember the downpipes / box were off a Thunder Ace , but they may have been off an FZR 1000 exup . I'll need to replace the downpipes / box soon , as they've been on my GTS for about 4 years and are now rusted out quite badly , when i get the replacement i'll let the list know which it was. atb Nick T --- Outgoing mail is certified Virus Free.
