How so?
Because there is little, if any power increase in a motorcycle that only the most experienced professional rider can use even close to its full potential on the street anyway?
Sheesh!
Buy whichever looks and sounds the best to your eye and ear and fits best with your budget.
You can do whatever your heart desires but to me it's a complete waste....
You are spending anywhere from $600-800 for slip-on's which in the automotive world is equivalent to mufflers only. That is a ridiculous price for something that gives a bit of sound volume, minor bling, 2-3rwhp, and drops maybe 3-5lbs.
If you are going to spend that kind of money, why wouldn't you just spend a little more $200-300 and get a full system. It will drop 30+ lbs. OFF the bike which makes it a totally different bike in the curves.....AND.....gives you roughly 10 rear wheel horsepower.
Heck, you can polish the stock cans to make them look chrome for maybe $30 in polish and take the baffles out for FREE if you want more sound! I'd do that LONG before I would even think about buying slip-on mufflers....
