i only know one thing ... sittin .. idleing will cause exhaust to come up around the rear and get into your clothes makes you smell bad. Its very similar to how the New Honda cbrs and DUCATi's are where they have the exhaust coming out the rear of the bike. When moving forward it creates a air pocket behind the rider , which in turns draws the exhaust back towards you. I know this for a fact cause I sold a 2005 CBR1000RR for this very exact reason!! Everytime i got home or went in the store people could smell the exhaust and I could smell it too. Taking off my jacket and smelling the back of it was like "DAMN, exhaust heaven!" was pretty bad!

 

Its extremely loud. Its annoying. It makes the bike look like it has an asshole. It sounds like shit. It gives the passenger a hot seat warmer. As for performance, I dont really care cuz everything else about it I hate. :rolleyes

 

I haven't heard a single good thing about that exhaust. The stock heat shielding is inadequate, and even with extra shielding, it can still burn your tail fairing. It's lound and sounds like shit, adds some odd bends to the exhaust system, and really cooks your ass. It also removes the little trunk space you once had, and on top of that, you have to deal with people commenting on how it looks like an asshole on the bike. No thanks.

 

from what i know, its lout and annoying, and it leaks....not what i want when im looking for a quality exhaust....all the extra piping would be heavy too...cross that one off my list.

 

The only bike that exaust looks good on is the ZX. On every other bike like everyone else said, it makes your bike look like it has an ass hole.
