Exhaust(?) sound

I recently bought a 2003 2.7 which is in tip top condition throughout.

However, I am hearing a noise / sound / note from either: near the side vents or further rear (not sure quite where), that sounds like someone blowing a raspberry!
I can hear the deeper noise of the exhaust, but there is a second "raspberry blowing" noise alongside it.

I can make it do the noise if I'm say, doing 35mph in 3rd of 4th and then gently accerate. It will do it at other speeds / gears etc, but this gives the most noticable noise.
The exhaust has been fully checked by my Indy, showing no leaks. I'm now wondering whether the noise is normal and I just need to satisfy my needs for a better sound with an Oettle or Hayward & Scott mod.

Any thoughts, advice, experiences welcome.
 
Weird. I've just had the same happen to me on Saturday. Raspberry sound when accelerating after gear change. Mine was more noticeble from 2nd and 3rd.

The good boys at Zentrum in Nottingham identified the problem to the bolts that secure the nearside header pipe to the cats had become corroded and allowed a crack to open up in the flange that joins the two pipes. These were removed and replaced and now the car sounds sweet.

That sound was so embarrassing when driving through town on a saturday with the roof down.
