I was looking into all the exhaust options, was curious to see if there are any exhaust that give a sport note similiar to the Fiat Abarths. I find that to be an excellent note where its no too loud but enjoyable and no drone.
Thanks for your input

 

The Abarth exhaust sounds great but the sound can't be repeated on a NA S2000. It is designed exactly like my old SRT4 was in that it has no mufflers, it just uses straight pipes and one resonator. The reason it works is because the turbo muffles the exhaust sound, if you did the same thing on a high compression NA engine it would pierce your ears being crazy loud. I really like the Abarth sound and I loved the sound of my SRT4, it was remarkably drone free for not having mufflers. I wish I could repeat it on my S2000 but it won't work.

 

Take a look at the UK exhaust mod, It gives more sound with no drone.

 

Another slightly more expensive option than the uk mod that is loud but doesn't drone is a custom exhaust. Use your stock resonators and whatever piping you want and run them to small resonators for mufflers and weld some stock exhaust tips on and you're golden. I'll post a pic of my setup tomorrow afternoon for you. It's a 70mm system and is pretty loud but there is zero drone and I was pleasantly surprised by that.

 

As another said on here, the UK mod does well... of course it can't replicate it but it still sounds decent, here are a few clips if anything..



and one with a resonated test pipe:

 

Do what I did. Buy an Abarth as a daily (well ours my wife dailys). They are great little cars but yeah the high revving 2 or 2.2 liter in the S2000 won't sounds like the Abarth little turbo engine. The UK mod may be the closest but it still is not the same sound.

 

Hmmm, lets see, do a uk mod for about $150 and get the closest sound possible for an S the op is looking for, or buy a whole other used car for like 10 grand...

 

I was joking I assumed the OP wasn't looking to buy a car.
