Looking to upgrade the exhaust/silencer on my yz450. The stock 04 doesn't seem to have a removable end cap for a spark arrester addition, and since I plan on doing quite a bit of trail riding and out at the dunes, it's somewhat important. Anyway, I am taking suggestions for a silencer that is arrester compatible, sounds decent and doesn't empty the wallet. Thanks for the help.

Pro motobillet end cap. I have one installed on my bike. I went this way since I race enduro's every now and then. Have not had any problems with it. I even got the silencer insert.

I have a fmf factory 4 SL with a gyt-r header, works good for me and cost a little less then the full factory 4 system.

White Brother E2 it is USFD and is 96db legal. You can remove the core for race and I tell you the differance in power is only noise

Loud dont = power

Go with dr. D step system. When you buy it make sure you buy the complete system.
I put it on my '05 and it made a big difference. It also has a spark arrestor that you can remove. I didn't have to re jet or anything. dubach knows what makes yz's happy.
