2001 2500hd - muffler enhancement
#11
Yes you will need to replace your old muffler. If you have two pipes going into the old muffler then you will need two mufflers and some form of another tailpipe to replace it. You will get your best sound running you tailpipe out from under the bed either out the back under the bumper or turned out behind the rear wheels.
