I have a stock 400ex 2001, and I want to buy a pipe. I want a pipe which is not noisy. I was thinking about hmf performance with a quiet core or hmf competition, which one should I take?

I have a HMF performance series. No quiet core. It is a load pipe. I like it though.
If you want a quiet pipe check into FMF quiet core
