Can i remove the center muffler on my 2013 porsche carerrra 4 without removing the rear bumper?

no

Explanation:

Unfortunately no, you cannot remove the center muffler on your 2013 porsche carerrra 4 without removing the rear bumper. This is due to the fact that the muffler has a heat shield which is attached to the muffler and in order to get to it for removal, the rear bumper must be removed first. Otherwise you will not be able to access the heat shield or by extension the muffler.

answer; ///first they would cross the atlantic ocean, and end up either in europe or africa; good luck
