2010 YZ450F exhaust system??

Sounds good but after adding a slip-on are you guys also adding a power commander (PCIII or PC V). I guess what I'm asking is that after you replace the stock exhaust with an aftermarket slip-on what else needs to be done

For me, it's runs so good (after installing the different muffler) I'm not messing with the GYTR tuner, or a Power Commander.

So, to answer your question, Nothing needs to be done.

That said, many guys buy the plug-and-play GYTR tuner to change it up some. A Power Commander is better for more fine tuning.

A LOTTA people aren't satisfied with stock, even though stock is good.

I love the way stock sounds but then again that was only in the garage, haven't had a chance to ride yet

Will a Lexx endcap open up the exhaust enough to notice a difference?

I thought I seen a slip-on for $600 on ebay. Besides the price and the fact that make great products what do we know about this pipe on this bike
It performs identical to the Yosh on the dyno. And costs twice as much.

Thanks for that info. The Yosh looks like it may also be shorter, is this correct?
