I noticed Graham at one point says bugger the noise and that he'll tame it down for track. I would suggest you go in Techieboys car for a run. He kindly gave me lift back to the hotel at the National and it was a truly horrible experience (not because of Matt whos a jolly decent chap all round) but purely due to his exhaust system and being in his car is not something I'd want to do for more than a few miles.
I like a bit of noise but my car can be totally quiet when you want it to be and fairly rowdy when you don't. I cant really advise on what you need for 300 plus bhp though as combos seem to come together differently and I'm running a weird mix that involves a Thorney manifold, miltek cat and 2tubular 2.5 backbox and 250 bhp.
Bargis exhaust does sound right and I'm sure is well made, but you might want to ensure that the visible part of the pipes at the back are to your taste.

I think we're all getting a bit older and yes, I like my exhaust noise but I would like to choose. So a silent system 90% of the time and a hooligan for 10%.
I/We need an active exhaust flap. Open for BAAAAAAAAAARRRRRRRRRRRRRRRRRRRP! and close it for trundling past schools really quietly. Shhhhhh
