So I have had the R6 header on my 09 for a couple months now and have several hundred miles on it. For anybody looking into an exhaust, consider doing it with the R6S header. IMO this is the most well constructed header ever designed. It has a perfect 4-2-1 pipe setup. Big long primaries, long secondaries and a good amount of straight section. I was worried about the lack of back pressure going into this project, but it has not been an issue. The bike pulls harder throughout. It is meaner than it ever was, and will get better with a PC. Bit of work to get it on, but not that difficult. Next on the agenda will be experimenting with better velocity stacks.
