Flowmaster does make stainless steel mufflers. Had one on my 03 Ram. 3" inlet, dual 2.5" out. I bought it at Summit and took it to the muffler shop. The stainless does have a little different sound then the plain muffler. Stainless tips will also have a different tone. I ordered the Mufflex single kit which will be here Monday. There are no shops around here that use stainless pipe. They say it ruins their dies.

 

Thanks for the input guys!!
