Flange Leak

DavidZ370

So recently I noticed 2 of my exhaust flanges leaking water... they are on tight with gaskets, is that normal? should I swap out the gaskets as they are a year old now?? (I searched to no conclusion)

Are you driving it enough? I'll leave it alone as I think that's probably just condensation.

DavidZ370

Yeah its a DD for now its weird I noticed it today, the bolts are tight as hell. I didn't drive it these 2 days though.

That does look weird, is it going to hurt anything if it's a leak pointing straight down?

I probably wouldn't worry about it. Heck people were doing the "washer mod" on this car anyways.

just get new gaskets or the gasket tube and redo. not a big deal as others mentioned.
and while tight can fix things gaskets dont always like super super tight.

Also check and make sure there isn't anything above that area that might be leaking on the exhaust.

I recently replaced my cat-back system with an aftermarket system. When I initially installed the system, all looked good with the exception of one flange that I suspected might be problem. After firing it up, I had leaks on all fours seals after the cats. The suspected flange had more issues than the others.

I wound up redoing those flanges with better hardware and applying cooper seal to the four gaskets. All turned out great.....no leaks.

Not sure if your leaks are from the OEM system or an aftermarket system, but do replace your gasket and/or add cooper seal.

Condensation within your pipes is normal. Water is a byproduct of your exhaust. Infact your mufflers have holes specifically for allowing water to drain so you down drown your exhaust system.

Your system should be fine. If you concerned about an exhaust leak, hook up a vacuum cleaner to one end of your exhaust system, cover up the other side, and turn it on and see if there's any air pressure around the pipes. You should be able to hear it if you have a problem. Otherwise I'd leave it alone and enjoy your car.

Can you please point out specifically where these drain holes you mention on the OEM exhaust. I can't find them.....

DavidZ370

Mine isn't oem

I know. I replied in an earlier reply regarding your post.

My question was directed at an OP who chimed in about drain holes.

New gaskets probably wont do you much good, my setup is brand new, and tight in every place, but it still drips a little bit from between the flange. I've done a smoke test and it's not leaking air. I wouldn't worry about it unless it starts to hiss, then replace the gasket, no biggie. But there's no point in tearing it apart for nothing yet.

Don't have a picture of the oem exhaust or know which exhaust you're running but this is an example of how small the holes are.

My AAM cat-back doesn't have any weep holes. Plus, I have the short tails so no muffler.

I looked at the OEM exhaust I removed and don't see any weep holes. I guess some car makers put these holes into them to prevent rusting especially those who take short trips. On longer trisp, the condensation buildup will evaporate do to the heat.

Hmm. I'll have to check my oem exhaust when I get home. If I recall correctly water vapor is a byproduct of exhaust gasses, it's not simply condensation.
