I have a fart can on the Integra (it was there when I bought it... because I put it on before I sold it to my brother then bought it back from him... ). It doesn't sound too bad... somehow better than a Honda even though it's the same thing. I just put the silencer back in so I can hear the intake.
FYI, it's the same canister that was on the Supra on page 1
Thats whats the funniest part is, If you have an integra, i'm sure you might know this but at some point in it's life it will have a muffler like that on it. hah. There was a type R with a muffler like this at one of the bimmer autocross'.
