I have a megan racing test pipe with HKS Hi-Power.. Review On Scale to 5:

Overall sound: 5
Throatiness: 5
Looks / Fitment: 4.5 (looks great but its a little off on the left side)

This is the best sounding exhaust I have heard on the s2000 next to the single Amuse Single Exhaust. There is absolutely no drone on the highway either and the Megan Test Pipe gives it a little more throatier sound (Plus noticeable gains). The fumes are not that noticeable and the do not smell that bad if you notice them (They do not linger in the car for any extended period of time.) Just keep stock cat so you can pass emissions test and you are good to go.

all of those "quiet" exhausts sound the same to me personally, basically just stock but louder a little.

 

talk about loud invidia+test pipe=OMFG LOUD!!!

but it sounds good

 

Toda has a nice bassy rumble to it and its half the weight of the stock system. It has dolphin tips so most people either love it or hate it (when you run a test pipe your bumper doesn't turn black )

 

I have that setup and still need to add an intake and header to try making it a little louder.
