Exhaust Note and a Jet chip?

Just got an S2000. I'm not big on the resonance in the exhuast so I think I'm going to put a cat back system in. has anyone heard a deep sounding exhuast on the S2000? I understand it is a 4cyl and probably hard to get something like this, I just want a good sounding exhaust and not a fart can.

I'm a little nervous... Maybe you guys could tell me the ones that do sound real high and whiny.

Also, Jet chips, I saw an add for one on the S2000 anyone have experience with this on this particular car?

Thanks,
