Can I run my stock 04' muffler without an insert? I have the GYT-R insert but when I pull it out, it seems to increase low end response.

Yes you can

It will reduce back pressue, and change the tuning

It will probably be too loud

Thanks. As long as I don't trash the motor, I don't mind the loudness right now.

So with reduced back pressure, do I need more or less fuel/air?
