The great change by switching to a full system MIGHT be a little less great for your bike.... (?) If I'm correct the catalytic converter is inside the stock muffler duo assembly and will still be as restricted as before.
I haven't heard these bikes with the SC mid-pipes/system and stock mufflers. Maybe the thing you pay for is looks....
Just wanted to let that be said
You are probably right but I love the look of the 821 Monster and I think the SC Project full system is a work of art, so I have to go for it. If I wanted more power I’d go for the 1200. Please don’t take this asa criticism of your post, I value ALL imput, even if I don’t agree with it.
