Is it ok to run the stock tail pipe with the whole insert removed? I've got the gytr muffler insert on order. Been riding with just the cone/spark with no insert at all.

That's the way I run it (AFTER rejetting and opening up the airbox).

Bike was tested at 95.7db today with no insert at all and all free mods.
