HMF Exhaust on YFZ
#1
#2
I've got an 05 YFZ with a HMF and know all too well what you mean about the noise. I added the quite core from HMF to it but it's still very loud even with that.
I ended up taking a small piece of metal screen and wired it into the front of the quite core insert where it goes into the pipe. This helped dramatically. I was worried it may have given it too much resistance and back pressure but I've been running it like that for 2 years now and no problems whatsoever. It's still loud but no where near the level of running the quite core alone.
