Annoying Rattle

[AdamJ]

If developed an annoying little rattle which seems to be caused by engine/exhaust resonance at certain revs. It happens between about 3500 and 5000 rpm. I think it's coming from behind the black plastic bulkhead cover behind the seats. Does anyone know if there's anything behind the cover that's likely to rattle? Also what holds it on as I'm probably going to remove it to take a look, which I guess is going to involve removing the roof and then the seats before I can get to it.

Could be your rear window, I had an Exige with a similar noise. They are prone to come unstuck.

Make sure none of the exhaust heat shields are loose.

[AdamJ]

Thanks guys, I'll check both

Also on exhaust there is bracket from tail pipes to main exhaust body these are common to crack and vibrate and rattle.

U bend heat shield between cat and exhaust is common source of rattles

Really interesting this, I have been in 2 or 3 Exiges which have had some resonance/tizzing at exactly 4,000rpm?! 

I look forward to the suggestions on what potentially causes this.

I had the rattle as Jon says

Yep I had the same bit welded up on my old exige

Reminds me of the anti-tizzy brackets on the S1
