Anyone tried this FMF Q4 mufflers before? Wanna use it on my 2000 WR400F!

How is the power performance using Q4?
Is it really quite?
Is the spark arrestor removable?

Loud pipes on the road gonna get me pulled over. So once I reached the woods/trail, will remove the spark arrestor and have fun ride blasting feel the power!

I'm running a Q4 and like it. It's not as quiet as I would like though. I wish I could get the stock sound level and still get the performance. I would like to have more of a turned down tip on it.

I wouldn't worry about pulling the spark arrestor screen out. They don't make any noticeable difference in sound and power.

Thanks guys for the input.

Hmmm... then what other aftermarket mufflers would you recommend to be use street legal? With a spark arrestor that can tame down the sound(quieter), and be removable to get more power/sound when go ride enduro/trails in the woods?

No spark arrestor will quiet a pipe down.

Many aftermarket pipes are available with a "quiet core" (FMF 4.1, FMF PowerCore, Two Bros) that is removable.

The Q4 is quiet all the time. There is nothing to remove to make it louder.

Do they have sound restrictions in Singapore?

The Q4 is quiet but many other pipes make better power.

The "quiet core" (FMF 4.1, FMF PowerCore, Two Bros) that is removable you mentioned, if its not removed it still loud right?

The Q4 is quiet all the time you said, but how's the power performance?
