Has any one ever cut down the sliencer on a 4 stroke? Like an inch or 3 ? I have heard of ppl doing it but never paid much attention, till i got ready to re-pack mine and thinking about cutting it down. I have a 05 yzf 450. Need some input. Thanks

I have seen people do it, it just makes the bike louder, I wouldn't recommend doing it.

You would be more likely to loose power than gain it.
