Poor guy who started this thread didn't even ask about performance gains. Its really very sad, all forums seem to go the same way. There are sound genuine people out there, who just want to help out, then there's people like this...

Thanks for providing me some info Remus backbox.
I knew replacing rear exhaust alone wont give much performance gain. I knew this fact even before I bought my IS200.
I just want to find out what people with Remus backbox think about the product.
and as I have posted, I didnt want loud noisy system. I dont want to spend money to have my eardrums damaged.
thanks for the feedbacks. very much appreciated.
