Stock Muffler with pin-hole leak at weld

[RTChall2010]

Last fall I was underneith the rearend of my 2010 RT Challenger (not winter driven) and noticed a black streak coming from the driverside muffler box and running/crawling down along the pipe that goes into the H-pipe.

Took a closer look and it looks like there's a pin sized hole in the weld between the muffler and the pipe going into it. I believe it's an improper/incomplete weld issue from the manufacturer/supplier.

Would never have noticed it if it weren't for the black streak which I atrribute as carbon which would leak out only on cold start-ups when there's condensation mixed in with the carbon residue inside the muffler.

Not sure how much of an issue this is to fix. I'm assuming all that needs to be done is a small weld to the spot. Most of the work would be disassembling the rear cat-back as welding in the area on the car would be considered dangerous as the issue is right next to the gastank!!

My question is two fold;

1. Is it reparable by just taking down the pipe and welding the spot?

2. This looks like a manufacturing defect and I've read stories on other forums that the welds on the stock exhaust have been defective from the supplier. I'm thinking Chrysler should be replacing this section of the exhaust free of cost. I know in the situations I read about in the forums, Chrysler replaced the pipes free of charge.

FYI, car is still within the 3-year body warrantee period.

Just get you some "JB Weld" at any auto parts store; mix it up, slap some on there, Walla ~ Done!

Good idea, but I don't think JB Weld can hold up to the extreme temps that the exhaust can reach. On the package it states the max is 300 degrees.

I did find something else on the shelf at Canadian Tire called "Liquid Metal" specifically made for mufflers and exhaust pipes. It'll hold up to 3000 degrees. It's $8 with a 4 hour curing period after which you take the car out for a ride to heat up the pipe and solidify the metal.

That should work fine. I've used JB WELD for tons of stuff.

Pic please. This might be the weep hole.

What sound does a "weep hole" make....does it sound like an owner crying when he/she has to spend more money on the car because of unexpected repairs? LOL

Make sure it isnt the drainage hole before you seal it up. Every stock exhaust system has them and they all form streaks.

There should not be a weep hole at a weld.

Sent direct from my BRAIN!

A pin hole? Ok you talked me down, ill give you $1500 US dollars for your car!!! Seriously I would not worry or waste good JB weld on a pin hole.
