I have just bought a WR400F, posted pic on this forum..

First comments are I need to change the pipe, bearing in mind I am in the UK what's the best to go for, how much and what jetting changes will I need to make...I'd rather it wasn't too noisey if possible...

I've got a Pro Circuit 496 and love it. It's 96 dB compliant and allows better power than the stock pipe with the cork removed.
