Do you have the NPP exhaust? If so then that's pretty normal since the outside pipes bypass some of the muffler. If you have the standard exhaust then somethings odd since they only have 1 outlet from the muffler to the two tips.

I have the NPP exhaust and the outside tips always require more cleaning than the inside ones do. I'd say yours is normal.
