Exhaust Question

[Kenna802]

Good afternoon,

I bought a r33 gtst about 3 weeks ago and the muffler on the back is a nismo/calsonic B0100-21U25. I have done a quick search on the net but have not found much info about them. Does any one here know any thing about them?

prob just the stock sport exhaust... go out and get an aftermarket exhaust

Well what do you want to know?

You already know you only have a larger than factory muffler... not sure what's lets to "work out"

what i was wondering was were they a good unit?/specs etc

i am looking at upgrading to a different exhaust but i always like to know a little about what i already have.
