I just installed a new stainless steel muffler a couple of weeks ago and noticed water dripping from the seam, on the edge of the muffler when it was cold. Is this normal? I came across the mention of ' weep holes' and 'weeping' mufflers on other forums. I don't want to put holes in the muffler. Is there anything I can do to prvent water and moisture buildup in my new muffler and exhaust system?

 

No, condensation is natural with all exhausts. Being Stainless means it won't rust so it will last. Air condenses as the metal cools from being hot from driving. All cars typically spit water every morning from this natural process.
