Doh, didnt read that right lol. It could be the clutch but as Jordy says if theyre the same noise then it isnt.
If it sounds like an old squeeky bedspring kind of noise, or an old squeeky door in a B movie its most likely that a new fitment kit is needed on your downpipe to centre section/cat join. The kit consists of two bolts and some springs, which squeek badly when they dry out. Theyre worst when you get torque surges through the engine, causing it to rock on its mounts, moving the exhaust and therefore the springs on the join. Which is why you hear it most when changing gear or accelerating, as the engine rocks longitudinally the most at these times.
Your looking at under a tenner for the fitting kit and fire gasket, and its easy to fit yourself if youve got two 10mm spanners, a jack and some axle stands.
It could be a number of other things, but the join is a common problem.
