Drain Holes or Leak on FRPP Dual Exhaust?

ponyboy643 · 03-23-2008, 09:46 PM

Took the car in a parking lot to take some pics and found the car was leaking from that little holes (see picture).

Is that normal? So that would be a "drain hole"
Or is it bad and that's a bad hole there?..

Thanks for help.

I just looked and mine do have two "dimples" on the bottom of the back side (facing driver) of the muffler... but I am pretty sure they are not actually holes. If they are.. they are only pin sized. My car is lowered.. so it's hard to get a good look. I stuck my phone under there with a flashlight lol.

There are no holes/dimples on the front side where the exhaust exits..

Thanks for the pics - it looks like the same tiny holes that I noticed on mine...

I guess that must be some drain holes, will have to confirm this with my Ford dealership next week.

Well, the single Flowmaster AT on my car right now does have a small, very cleanly-drilled hole in the underside of the exhaust tip, which I assume is for drainage purposes.

On the other hand, the Borla Stingers sitting in my basement do not have any holes of any kind in the exhaust tip, so I'm not sure.

I would assume the little holes in your mufflers are there on purpose to allow any water that gets in the muffler to drain out, probably nothing to worry about.

If it is a hole it is to allow condensation to escape from inside the muffler. Some mufflers have them,some don't.
