Norfolk specialist / Quicksilver vs Lotus Stage2?

[shot2bits]

Hi All - I'd almost decided to go for the standard Lotus Stage2 exhaust with fitting at Strattons. However, having read Fish's comments on the Quicksilver plus ITG, I'd be interested in any recommendations for a local specialist to perform fitting for me? I'll also ask Strattons to see if they'd be happy to do the work...

As far as I'm able to make out, the Lotus Stage2 does not offer any performance increase but the Quicksilver does...? Or... is it the ITG producing the extra torque?

As far as noise, I do want it loud but it's the quality of the sound which is also of interest - i.e. don't want it to sound as if the exhaust has blown!

Davey - you managed to sort out a recording of your stage2?

Thanks in advance...
