Re: GYTR+Mid Pipe+k&n
Its a pain to remove in my opinion... but some claim its not that bad. That is why yours isn't overly loud though. That will also mean the volume its at, is pretty much it will be as you won't detoriate/"break in" the exhaust packing.
If you want it louder, removing those cats will help. However if start removing it, you have to get it all.
