FMF powercore 4

Well i picked up my pipe today looks really nice im going to put it on the bike this weekend .....i wonder how its gonna sound

LOUD, then louder, then will blow out the spark arrestor screen! :lol:

On the upside it will make more power than the stocker, but so will a straight pipe, which is what it sounds like after a couple thousand miles! Oh and when the isolator strap either melts or falls out it will rattle like crazy! Oh, welcome to TT

They make a quiet core insert that shuts it up without choking it too much.

I got about 150 hours on mine and it still sounds sweet.

well it says to repack every 30 hrs. i can imagine if u didnt maintain it it will give u issues ...maybe thats what happened to rebelventurer???.

I also have one and the insulator strap melted/fell out and when i discovered it the can had a nice wear mark from the clamp rubbing. The strap design is very poor. Why not weld a tap on like procircuit T4? It also leaks. Other than that i think it sounds pretty good.

I agree rebelventurer. I'm not a big fan of FMF 4 stroke pipes off the race track. Most of the sancioned group trail or dual sport rides around here a lot of FMF's fail sound check for just the reasons you give. Screens missing from the spark arrestors or just plain tooo loud because the packing doesn't last very long.:ride:

I've installed quite a few and had to do repairs on many of them. They do seem to make real decent HP though!
