I noticed there was water coming out of a round hole that looks to have either been made that way in manufacturing or was drilled, (definitely not rusted through), in the lowest part of the vertical flat front part of the muffler. The muffler is OEM as far as I can tell. I looked up a replacement in the walkerexhaust.com website and they say:



-------------------------------------------------------------------------------------------------------------
WALKER QUIET-FLOW® SS MUFFLER
Walker mufflers feature precision fit, superior flow, and OE-style sound. In addition, these mufflers include 100% stainless steel heads, shell, bushings, louvered tubes and partitions.

  • Precise OE-style routing & hanger positions for quick & easy installation.
  • Comprehensive internal drainage system for corrosion resistance.
  • OE-style domed heads help reduce radiated noise compared to flat heads.
  • Spun-locked heads to help prevent rupture.
  • Limited Lifetime Warranty and exclusive 90-Day Safe & Sound Guarantee.

I have also done a very minimal search on YouTube and found a couple of 'interesting' videos. Particularly these 2:

Does anyone know what WalkerExhaust means by "Comprehensive internal drainage system for corrosion resistance"? or has anyone here have professionally worked in a muffler shop and; 1- know about "weep Holes in exhaust system as OEM?... ...and 2- would that pass emissions or safety inspection in all 50 states here in USA?
I have never seen such in my many years of auto experience.... ...Quite strange, but I can see the reasoning behind it, but now I am rather confused weather or not there is supposed to be that so-called 'weep hole or if it will cause a Fail on a State emissions inspection:oops::eek::rolleyes:

Also: I am familiar with the condensation issue and always make sure that the exhaust system has heated up enough for the 'excess accumulation of condensation to get steamed out before I turn the engine off so it does not cause water droplets to form on the cylinder walls from the exhaust system and cause premature wear to the piston rings and/or cylinders.;) I know some might think that is weird or OCD, but I have seen pitted cylinder wall damage caused by rust 1st-hand; not pretty. It is concerning to me how fast rust can form on cylinder walls.:eek:
