OEM, Fuji, Mugen. There was a group buy for the Fuji. see if its still going on.

 

OEM, OEM/ukmod, Fujitsubo Legalis R, Tanabe Hyper Medalion

 

Fujitsubo Legalis R...best bang for the buck for a quiet aftermarket exhaust.

Edited:
I'd say it is just slightly louder than stock

Neuspeed is quiet, but it's only 30lbs lighter than stock.

Mugan Ti is really nice, but as mentioned, expensive. My used S came with one and I love it

 

Stock exhaust with a boost cutout for the win

 

ASM Siren

Hands down the best S2K exhaust I've heard. At no point is it ever obnoxious or overly loud. Similarly, when you do punch it and want to hear something - WOW!!! Videos do not do it justice.

Other s2k exhausts i've heard both at the track/street.

-HKS Hi-Power
-T1R
-J's Racing 70RR and
-ASM 70mm
-Greddy Spectrum Elite
-Berk 3"
-invidia N1
-Invidia Q300

Good luck though. They don't come cheap. Build quality is top notch. It uses the hohenheim design.

The only reason for an aftermarket exhaust on this car is for sound. You aren't going to get any power gains, and thats not a very cost effective way to save some weight.

So if you don't want a loud exhaust, just a nice sounding exhaust, then the uk mod to the stock exhaust is the way to go.

 

Where can I get it?
