Default Possible exhaust leak?

On my 06 G coupe i noticed there was water dripping between the muffler and midpipe where the two connect. I only notice it on cold startups when there is condensation. Also noticed no change in exhuast note. Is it normal for water to drip from there?

It's possible that a leak may have formed there over the years. If there is no noticeable leak other than occasional water, I wouldn't worry about it. I don't recall if there is a gasket there but if there is you could replace it. Or use something else to seal it. It's not going to hurt the car.

Water can be a byproduct of the combustion process. Ever notice water dripping out of your exhaust when you first start the car, especially when it's cold?

Condensation is the main reason for the water you see.

If there's no tone change, no tick, no noticeable cracks, holes, or bends then you're in good shape.
If you want to feel better about it you can change the gasket but i wouldnt bother, if not done properly you could end up with an exhaust leak after the work is done.
Water dripping from exhaust is normal. Mind your weather conditions when you see the water drip.
Is it cold? is it humid? is your underbody wet? I've heard nothing of a drain hole in the factory exhausts but i suppose it could be possible.

that water just usually blows out the tip. I dont see design intent to have a pinhole before the muffler. I think that joints just gets weak.

It should be a sealed line to the muffler. Exhaust leaks aren't designed into the system.

On my '05 Sedan, at 100,000 miles the only exhaust pipe leak was at the muffler flange to the mid pipe. It is the one that has a ground strap attached to the flange. Just touch the ground strap and it fell apart. Both sides of the flange were rusted and the exhaust note was louder. Took it to a muffer shop and they welded a nipple in place of the flange.

Water dripping from the muffler is normal but I don't think it should be dripping from the flange. It is probably beginning to rust away as mind did.

Should I attempt to replace the gasket? Is the gasket just a metal o-ring? My exhaust isn't rusted.
