This is for anyone with a quiet A8/S8 like mine. Before I did this my car sounded as though the engine was powered by air, no matter how hard I pushed the pedal, no V8 sound came out of it ever. I then drilled the airbox and OMG what a diffrence, theres a deep low V8 grumble (you will know what I mean when you do it) I was out all last night driving it with a grin on my face, turns heads everywhere and sounds goregeous. I didn't expect it to make such a diffrence, I thought it would be more a case of 'I think its a bit louder, ermm maybe, could just be my imgination' but this has totally transformed the sound of my car and saved me a hell of a lot of money, I'm not going to bother with an exhuast now for a while yet. My advice to anyone with an 8 is to do it.
I did do it to my A8 but couldnt tell as my quads with no silencers saw to that.
One thing I did notice was that when I drilled my 97 A8 it didn't have a air pump, in the airbox at least (I think thats what James called it) but my 2001 S8 did, all I did was disconnect it to take the airbox out. I will do my 96 A8 when its back on the road to let A8 owners know what it sounds like, although I imagine it would be much the same. A deep V8 grumble

EDIT: Forgot to add that when driving normally, it sounds like it normally would. Its only when you boot it that the engine sounds so good, about after 3k revs you get the most sound I rekon.
