MGP slip on is easy to install. They range brand new from $210 for just the canister to over $500 for the entire exhaust system. You can fact check it. Very loud pipe. It's on a Kawasaki Ninja 300 right now and it gave me that confidence I needed riding a bike in the lightweight Family of Motorcycles instead of middleweight or heavyweight. If you starting out small like I did on a 300 or less then add this slip on to your bike and you will see the difference in the sound. Or if you just like bikes with smaller engines,this is a definite add to go on ride outs. Not sure if it will fit 500, 636, 750,or 1000 motors, but Google it and see. I think it is a Universal pipe though.
