All 2st muffler repack vs horsepower

Has anyone experienced a difference in horsepower related to how the silencer is repacked? For example if you use the 2 stroke FMF packing that is bagged loose and pack it tight compared to simply cutting the sheet type of packing to length, giving it a wrap and buttoning it up.

I did my FMF power core a few months ago with the shreded 'Pink' FMF stuff. What came out was the sheet wrap stuff. My HP feels the same but the bike is quieter. The key on mine was the baffel. Almost very little hole was plugged with spooge making the packing useless. When I repacked mine, I didn't over pack and wrap it super tight. Again, no HP difference.

I've got some the the sheet stuff and want to repack before riding very much with the new Lectron.... which will defeat the purpose of any comparison. Maybe I should ride the goopy silencer first a couple of times, then repack and compare. My silencer/pipe are both stock. I'll wait and report back.

Loose vs Sheet ... no real difference Doug but it depends on how tight you pack them as JHunter points out. Personally l don't like the loose stuff as l don't have a good feel on how consistent the packing is...last time l packed with loose stuff it ended up being an addition to exhaust gases before the premix held it together, then l had a hot spot where there was no packing - IMO, the sheet stuff is easier!!

I tried the loose stringy stuff a while back. Caused me to fail a 98 dB sound test. I took the muffler apart and could see why. The packing had become so stuck to the perforated tube that I had to chisel it off and then use a propane torch to finish cleaning it!
