Leo Vince corsa GP exhaust on the ninja 250

[Mitchell Klein]

As the title states I am running this exhaust on my 250, I am running a little rich right now with the silencer in place. If I removed the silencer, would it lean out a bit? For those running this exhaust, do you run the silencer in or out? Any power difference?

[David Roy]

Run out for sure. Would be best to have a profession jet it for your mods.

I had David tune mine with that exhaust and it made a huge difference! My bike is very fast now - I can catch Jim Whitten in the straights, now I just need to keep up with him in the turns. Well worth it!
