The exhaust sound from a big 4 stroke will also carry farther than a 2 smoker for example.
I am sure my SuperTrapp is not the quietest pipe option, but I keep the packing fresh and have played with the disks and found the compromise between quiet and performance I can live with. Like to know how that app works.
That's essentially what I'm trying to do. I want decent performance, but not overly loud. The factory insert, even after modifying it a little was very restrictive. I'm happy with the performance of it without the insert, but it's a bit loud. I have a friend of mine welding up a turn-down for it right now which should help a little, but if I need it quieter than that I'll make a custom insert (like the old re-packable Thumper Racing inserts).
If I had an extra $300 I'd throw down for an FMF Q4, but I don't have the money. When I got the bike it had a god-awful loud old Supertrapp IDS that fell apart in multiple pieces when I tried to repack it. Picked up the 600R muffler for $30 shipped to replace it.
