Just put a Patriot Racing Exaust on my 2011 450R, the pipe has unbelievable flow it sounds like a 700 Raptor with aftermarket exhaust. It is designed with a 4 stage header and a 2 stage silencer, my question is... I plan to check to see how lean its running, but how does the bike's fuel injection compensate for a pipe with very little restriction, and should I consider plugging it up slightly with there optional reduction insert?

If patriot is building pipes, you can probably bet they're doing maps too. Call them. Id think they'd be able to remap your ECU for very very little money.
If not, call Eddie Sisneros. He can do it and will work with you too.
