I got my new FMF Factory 4.1 slip-on today. Install was easy, took about 2 minutes.
Have a couple questions I'm hoping someone here can answer.
-- Is there a quiet insert for this exhaust that also comes with a spark arrestor?
-- I have a UNI filter but haven't done any mods to my airbox lid yet. Should I wait to mod my air box until I get the powerbomb header and an EFI controller or should I do it now. I have a buddy who has a cnc mill and he was going to make me some cool plates to use for my air box mod when I do it.
-- I didn't use any silicone on the initial install but I ordered some today and am planning on applying it before I go for my next ride.
This thing is damn loud, I expected a difference but this thing really cracks the whip. My neighbors are going to be pissed if I race it up and down the road much more.
Spark arrestor is a must have for me because I ride on lots of public lands and it's required. The best of both would be great, I know this thing is well over 100dB and I really don't want a ticket.
How does a spark arrestor and quiet insert affect overall performance?
Thanks for any advice or comments on this.
