Just fitted the remus headers and K&N filter from my 07 GSA onto the 08 bike. On the previous bike there was a noticable difference in power delivery, particularly at the top end.
What surprised me was that I couln't really tell any improvement on the new bike. Posssibly its still a bit tight at 2500 miles but I suspect its the changes that BMW have done between the two models. What I did find was that the exhaust note became much more intrusive on longer runs, irritatingly so. But perhaps its what they call age!
It will take a minimum of a 10% power increase to feel it and the Remus/ K&N setup doesnt meet that requirement.
I have just taken the headers off and returned to the stock system.
Save your money, if you want more noise buy and end can if you want more power look elsewhere IMHO.
