Downgrade wr250x

I love my wr250x, but I hate the exhaust. It is too damn loud. I literally go deaf after riding for few minutes without ear plugs. I would love to switch back to the stock exhaust, which I have. I don't mind sacrificing performance for fuel economy.

Can someone help me understand what is required in putting back stock exhaust and any fuel reprogramming required. How complicated is it to do? My bike technical knowledge is limited but I don't mind tinkering.

It may not have been remapped or rejetted at all.

Put the stock exhaust back on and see how it runs.

Thanks for quieting your bike down.

I put my stock exhaust on after running a FMF Q4 for a while. There was no change in performance, just a large reduction in noise level.

The main thing you'll have to do is re-connect the exhaust powervalve (EXUP) cables. Hopefully you didn't remove the whole servo motor.

It's under this stainless-looking cover, below the open airbox door.

Thanks for the info guys. I will tackle this project sometime soon. I was worried about having to having to reprogram the fuel programmer. I will just change to stock exhaust and see how it runs..

I would throw my stocker on when I wanted a quiet bike....didn't bother with exup or any of that. I had a power commander IV so it was just a matter of switching the mapping back the map appropriate for my setup. I was actually able to keep the mega bomb header on to maintain a little more grunt.. The top end was more choked but it was great riding without earplugs.
