I have th 08 WR 450, have done all the initial modifications.
It can climb steep single tracks very well, I live in Montana.
I'm considering an exhaust change and maybe new sprocket gearing.

front or back sprocket change?? I don't know.

does an aftermarket exhaust really make much difference?
does it truly add power or is the stock unit fine?
I want to enter an enduro this summer.

I put an aftermarket pipe on my Harley SuperGlide and the performance is worse than stock. With the stock muffler the Harley has much quicker acceleration from a dead stop. the aftermarket pipes just sound cooler, it think it drops power. Of course none will admit that, or maybe they can't notice. the aftermarket slip on pipe was a waste - but it does sound cool

I don't want to do this to my WR.

Thanks for any advice,
Erik

Erik,

As far as gearing goes, the rule of thumb is that 1 tooth on the front sprocket = 3 teeth on the rear.
I'd be trying a 1 tooth smaller front sprocket first if I were you since this is a cheaper option than buying a rear one.

Exhausts? Check this out before you go wasting money on an aftermarket exhaust....... (It's a lot of reading, but very informative.)
