So a friend of mine is picking up an S2000 and it has a couple of mods on it; one of them in particular is an MG Racing Exhaust, dual canisters. The owner of the car says that the exhaust is rare and discontinued, I on the other hand don't know anything about it and was wondering if you guys had any insight on the exhaust?

It'd be a lot of help, thanks.
And if you're interested in buying it; my friend plans to sell it anyways.
