I have an after market silencer on my Husky with the stock pipe. The FMF silencer is MUCH quieter(good), but the top end power has fallen flat(bad).
I met a guy on the trails recently who had the same bike as mine. He said he had cut about four inches off his stock silencer and it had really "woken" the bike up.
So I started wondering exactly how the silencer affects tuning. I think I understand how the "echo effect" in the expansion chamber keeps the fuel in the cylinder longer thus increasing burn efficiency. What perplexes me is how the sound waves at the point of exit affect performance.
More specifically, I'm thinking of experimenting with my silencer packing. It's seems to me that I could maybe just pack the forward half of the silencer then try the rearward half all while keep my perfectly good FMF hardware intact.
I know, I know... "Louder isn't better", but I do have a little leeway to play with.
So, does this sound practical?
Is there a more scientific approach?
What do ya'll think?
