Wr 450 Exaust

Is stock exaust with a pmb insert good or is it worth putting a pipe on. Noise is not a problem and I am looking to get more out of my bike and dont know what to do.

I run an 05 450 and tried the PMB silent insert. To be honest I could not feel improvement in power at all.:eek: Others on the forum claim it works but personally I felt nothing. I removed it and went back to no insert for a while.

If, as you say noise is not a problem I would replace the end can.

So many to choose from, I went with the GYTR. Now that does give more power :thumbsup:

I tried the pmb insert and removed first baffle, a bit better but when i put a used Yz muffler on i loved it, way more power everywhere.
