I *believe* that the right side on the 650 is the CAT. The exhaust goes in and comes back out to the left muffler.

True, but the fact is, the miniscule differences in weight we're talking about here aren't worth mentioning, let alone worrying about.

The general rule in drag racing is this: All else being equal, 100 lbs. of additional weight = 1/10th of a second added to your ET in the 1/4 mile. A 100 lbs. reduction would equal a corresponding lowering of your elapsed time.

In the case of these bikes, five or even ten pounds will make negligible differences in performance.

In other words, if you like the look and "coolness factor" of a dual exhaust, go for it! Any additional weight involved is not going to affect your performance by any discernible degree.

The license plate holder and the red light attached to it (below the stock brake light).

Performance has multiple levels: next time you drop your F8 offroad and have to pick it up you tell me if you care about an additional 10lbs. Or if you're plowing through deep sand or mud and would prefer a lighter bike.

Seriously, weight matters. I don't see why this is so hard to agree about. We're not talking about 4 wheeled vehicles with big engines, we're talking about two wheels that already weigh more than they should that you ride offroad. If you never ride offroad then sure, 10lbs isn't as much of an issue but if that is the case then why buy an F8.

Because an F8 is good for more then just "off road"

I will just stick with my tool tube with a bottle of Jameson whiskey in it. A few sips after a ride and you always think you were faster than you really were.

Coming from riding (and occasionally dropping) 800+ lb touring bikes for decades, my opinion is that if 10 lbs is going to make the difference to you or anyone else, on or off-road, on a bike that is still going to tip the scales at under 500 lbs, then it's time to throw in the towel and head for a nursing home.

Cool looking bike. Can you give me some info on how you did that exhaust system. Did you keep the existing headers with a 2-1-2 system or did you go 2 into 2 straight. Also how did you manage the o2 sensor?
Thanks.
