When doing my biennial brake fluid flush, I was surprised to find a hole developed where the tailpipe joins the muffler body. I am under the car much more frequently than very two years doing maintenance or inspections, but I never noticed this developing to this degree before. The rest of the exhaust from the header back is pretty darn clean. This is an 02 Lexus ES. In our climate, rust is a non-issue and this is the only spot. Seems like an obvious condensation trap there.

I have searched quite a bit on exhaust repair techniques but I can't find something I see working in that angle. The material around the hole itself is brittle and you can poke it and flake it away. I imagine it would need to be a putty or paste of some type initially to form and adhere. Also, the pipe is quite corroded and I think if I used a wire brush on a drill to clean it up it might erode it away.

So I was wondering if there was an inexpensive way to patch it that would last vs buying a new one? If a patch would only last a year or two, it's certainly not worth the effort vs. replacing it.

You can't weld to rusty metal so, no, there isn't a halfway fix.

You can call some area muffler shops and ask them how much for a new muffler with tailpipe installed. Then ask what brand they use. Should be around $120-160. You can wait till it starts to get louder, may last another year or so.

Side note: always make sure your mufflers have a clear open condensation drain hole.

So if the replacement doesn't have one, should I drill one? (drain hole).

Between Bosal and Walker, which appear to be the two widely available choices, is one superior to the other?

I see that I can get one or the other for about $150 and I can install it.

See what a factory replacement pipe costs before doing anything.

Definitely worth it to drill one if it lacks it.

Heck, here in Wi that would be listed as "newer exhaust" on Craigslist. Looks clean by our standards.

They were $360+ shipping at the best price I could find. A super-clean take-off from a Texas or other dry-region wreck is not unacceptable to me. I will also shop for one, now realizing I can drill a drain and make it last longer. This is the only muffler I've had to replace on any vehicle living in the PNW given the mild climate/no salt. Even though it has high mileage, it runs great and looks good. Probably the car will stay around in use and then go to a child in three years when they start driving.

A local guy near me welds stainless pipe and not much more than steel pipe.

Looks like aluminized muffler (good) but plain steel pipe (bad) ... Make sure the new one is aluminized all the way back smile

Get the sawsall out cut out and replace muffler and tail pipe. Any less is a temporary rig job.

Get a Walker Quietflow muffler. It's stainless and has a lifetime warranty smile

No fixin a muffler like that, it's where most fall apart. Check Rock Auto. Great prices just make sure everything comes from the same warehouse or shipping stacks up.
