I have recently thought of getting a new exhuast for my WR426. I have always said I didn't need one because the bike was fast enough and the exhuast is nice looking. Now I am starting to think about the weight difference I might get. What kind of weight difference have people seen from stock to aftermarket? Could you feel the difference? It seems like a couple pounds of loss off the top of the bike could make a difference. Thoughts? Should I be looking elsewhere for my diet?
