it's not always the heatshield, cat also does the ratte at certain rpm's (2.5k?).
mine used to rattle after I modified it.

i just cut the cat out en put a tube as replacement ... simple and cheap.
I suggest you replace the air intake, if you just remove the cat you will win som HP but lose torque, if you replaces the intake you win like +-20Nm and +-20hp on a 1.4 engine

you lose torque when you decat??? I didn't know that...
you're saying a performance airfilter and cold air intake will fix the problem?

I couldnt tell you where but there is a known issue with part of the exhaust vibrating at those revs, mine did it new cat and a few hours messing still rattled

Some messing about by the garage and voila fixed.

Apparantly my grandad said he heard a rattle on my dads 400 when it started up - I havn't noticed it. But when I was in it the other day you can hear a rattle when pulling away at certain rpm. Its very quite but we both noticed it. I "think" this is probably a sheild? Could be the cat breaking up.

Mine was a git for this annoying rattle at 2700rpm drove me mad as it happened at motorway speeds obviously. Took it to saeveral places some said it may well have been the auto box -brown underwear !! Later to an xpart centre new cat rattle at 2500 rpm now!!! 3 mechanics ragging it down a lane 2 with doors open head under the car fixed heheh exhaust mounts towards back of the car -amazing how the sound travelled

BTW the cat OEM was £495 (nearly died) they got me a non oem one £80
