Well HKS is more high-pitched and Tial just sounds gassy, if you know what I mean. I have a Tial Q and love it. Although I'm curious about other options for different sounds. But that Tial Q holds boost pretty well.

 

thanks for the all the answers, my freind has an hks on his subie and its LOUD. i dont want it to loud but i dont want it unheard either. i heard the tial is very quite.

 

When I was passing a stage 2 sti at the strip, he said my car was so loud he thought his car was broken. turbosmart ftw.

that nuke stuff looks pretty nice

 

Synapse synchronic bov. No diaphram, pull style. Diaphrams can fail and dont work as well.. you want function more then anything. If you want the cool Turbo sound save yourselfs tons and get a Turbo muffler. Cool sound for $100

 

I am running a TiAL. Use a BOV for function not for sound, TiAL functions better than HKS.

 

The best part is that they special make bolt on parts if you order a bunch, really easy to get in touch with the guy that make the parts.
Good to know if we need a certain S2000 part in the future.

I use their fuel filter as well:

 

Tial and hks are great. But for $210 shipped, no diaphram, and won SEMA awards. Pricless lol I'm not hating I'm just backing my bov lol
