hi guy does anyone have experience of the two brothers ? what quality like? sound do they need a juice box or power commander to run right? thanks peoples
They're not very popular over here, but our American pals tell us they're crap and yes they do need a PC or similar to run right.
Not a fireblade, but had one on my 600rr. Quality was not bad, Sound was great, very loud (which is what i wanted) but eventually the police kept stopping me (London) so i ended up getting an akrapovic. As JM1 said, the americans tend to hate them, but i personally found the quality decent, sound good and looks wise not bad neither. However, it did make my bike run very flat, no power anywhere through the rev range, so i ended up getting an akrapovic.
