Just hopped back on my 450 yesterday and the stock exhaust is extremely loud. I ride my gas bikes with earplugs but my right ear is still ringing after 3 30min motos. Can anyone recommend ways to quiet the bike down? Is there an aftermarket exhaust out there for the 2012-2015 KX450 that is much quieter than stock?
The Shop
They included a spark-arrestor insert (a cone made out of wire-mesh screen).
That little insert made the bike much more pleasant on the ears, plus it actually helped the power delivery at initial crack of the throttle on that bike which was terrible on that 2014 model.
Without the insert the PC silencer seemed slightly quieter than the stock Yamaha one.

Our exhaust systems meet FIM noise limits, feature a more durable welded bracket and titanium end cap.

Kawasaki's are loud and annoying stock! They sound like they need repacked. The 250's are bad as well.
I'm not seeing a FMF Q4 Hex available for the 2012-2015 KX450f. Does anyone know if 09-11 KX450f mufflers fit the 12-15? I see other exhausts available that list 09-15 KX450.
Does anyone else make something quieter?

“What does it sound like?”
So, I started it.
“Damn! That’s quiet!”
FMF 4.1 RCT w/ the Sparky installed. I race it that way, too. Sooooo quiet.
But, if indeed you are fair dinkum, I bet it still , sounds Great. A bike doesn't need to sound obnoxious, to sound lovely.
My CRE500, with my 26"Long muffler I made, so I don't attract attention in places that I've ridden in for over 45 years, is almost silent at low revs, which is what is used in my tight single track, but, it sounds nice and deep, like a 500 should, at higher revs, without being an ear destroyer. Though, you can never get rid of the "bucket of bolts", "Crack Crazed Chook Cackle" that a Big 2t has, under no load..........
Quiet is good for my ears!
I want to ride your CR!
I had no use for more power on a 500. With the stock constricted exhaust, I have all I need and more.
