Different bike I know but I have a scorpion serkit on my 8 and run with the db killer in.With it out it sounds great but the lack of back pressure creates a loss of low end torque but it's cleaner and smoother above 6k. As for sound, from my perspective without the db killer it howls but the wife said she can't hear it from the house or when I passed her car at 'legal speeds'. Friends following have said that it's loud but but not offensive.
Same sort of exhaust by the looks of things.It'll sound totally different, but according to my Dyno mechanic you'll never beat the original stock exhaust for best performance.I just don't like the sound of them, they're a bit too quiet for me.

A more free flowing exhaust still has benefits?Car engines are usually "restricted" from factory, to suit the majority of the buying public. Restricted via their firmware/software maps (ECU). People remap them, to get a bit more performance out of the engine (which can actually also increase mpg).We don't have any equivalent capabilities with the Fazer?I suppose my main reasons for this change, was the increased noise (more road presence = SAFETY) plus cosmetics to compliment the Naked styling, losing that big long 1/2 metre cylinder for a much more sporty, compact unit. I'm not maintaining this bike to look like it just rolled off the production line.
