KX125: PC 304 Shortie vs stock muffler?

My nephew's '05 KX125 has a ProCircuit R304 Shorty on it. I've also got the stock silencer for it. Repacked both tonight.

I was wondering what the noise level and/or performance difference might be between these two silencers?

Quieter would be better on the trails....

Thanks!

Stock is less "offensive" in the sound department, but the Shorty gives a little more power down low.

Kind of what I figured might be the case. I think the best way to test it will be to get my nephew to ride back to back with both pipes....I can then judge the sound level and he can judge the power...then figure which one to keep.

Both should be quieter now that I've repacked 'em both. At least until they get gooped up again. :thumbsup:
