Well thought I would let you know that after having the ME Kit sitting in my garage for about a month debating whether or not I should rip the muffler off or not finally did it yesterday! I am just sorry I waited so long. It really is not that bad, crusing in OD it is about the same as stock, when under a load you notice it, and when idling you can hear it a little louder at the tip. Just thought I would update you.
