    So today I noticed a small fluid leak as I came out to the truck this morning. Found a moisture/water drip from the muffler. Looks like a seam not running from any other location. What's bothering me is that my DTC shows incomplete under the typical emission items. Odd but I did have the battery disconnected the other day and may not have driven enough for it to complete. Anyway, pics attached - no issue or definite concern?

    I just replaced a muffler on a 2000 4runner. Muffler guy mention instead of drain holes they weep at the seams.

    Thanks. I actually think this is nothing more than a brain fart moment. I had the engine idling and truck was backed into the driveway - so incline. No place for any condensation to go but pool. So what you mentioned makes sense - muffler was 'weeping'.

    Oh well. Will monitor for now and update if any weirdness occurs - thanks!

    I wish our trucks didn't need those stupid weep holes...i just put a brand new muffler assy on not too long ago and since the first start the exhaust sound like shit. Sounds like a straight up exhaust leak and it's coming from the weep hole. I put my finger over it and it is quiet. Ive gone through 2 mufflers now doing the same thing. I was almost thinking about welding that thing shut but seeing as 6 months later the "Stainless" muffler is already starting to rust that would make it rust even faster...

    My magmaflow muffler does the same thing, leaks at them seem. And drips at the exhaust tip if I leave it running long enough

    Nice, do you have an ebay link to the third one? When I click on it in torque lite it just brings me to the ebay default page with 1,000,000 different chineese bluetooth adapters!

    The elm just sends the parameters to the phone/app. The app does the rest.
    Enjoy

    Same issue though, it would collect moisture and rust out. Just the design is crap.

    I think your muffler bearings are going bad.

    Should I change my exhaust fluid?

    Water condensing in the exhaust system is 100% normal. The problem comes if, like me, most of your trips are too short to get the entire exhaust system up to temp. I've gone so far at to drill my own 1/16" weep hole in a replacement muffler that lacked one. Personally I don't give it too much attention, replacing mufflers is just part of owning a vehicle.
