Default 99 si loss of power

i have a 99 civic si that seems to have lost an amazing amount of power
i did have a honda specialist take a look at it and he told me it needs a new clutch but im havin a hard time believing it
it does not slip at all but when i get into higher rpms i can hear something clunking around inside the engine bay
it seems like the car just doesnt want to go


but how could the clutch cause that??

you need a clutch, that is what's making it hard to go into gear.

you need to replace your catalytic converter, that's what's making it slow.
