I kind of understand that. I had a BMW R1200GS and I did consider swapping the standard Exhaust for an Akropovich Carbon one. It wasn't quite loud enough but the performance was fine for me but when I looked up the price I thought, what the hell, the originals ain't so bad

. I quite like the sound of the R3R. Distinctive and not trying to have the Harley burble. It is a sound of it's own. As for performance.... There's plenty there for me, and some!
