Can you reuse welded tips ?

I would like to see what everyone sees is the typical life of a stock muffler.

Why, I am wondering if it is worth it to throw on welded tips if the muffler will be trash soon @ 82k miles?
Leading to another Q, can you re-use welded tips once they are installed and eliminate these questions all together?

I replaced the stock muffler at 110K on my 2000 Maxima last month. I live in Minnesota, so my Maxima sees a lot of salt on the roads which doesn't help muffler life.

it depends on where you live. if you live in florida, it can last a long time. but up here in the north east, we see snow. so that means salt. so it will probably rust away depending on how often you wash the bottom of your car during the winter months. your better off getting something stainless.

Good question

This question is ironic in that my 01 GLE stock muffler setup just went Sunday at 98,000 miles....The flange closest to the muffler finally rusted away thanks thanks to Ohio salt/winters....I went to a muffler shop and had them cut out the flange and weld a sleeve to put the exhaust back together for $30....Other than that one problem the stock muffler set up looked intact as I inspected it with the mechanic...

So I am wondering if it is worth it to throw on welded tips if the muffler will be typically be trash soon in 1-2 years?

the muffler is going to be fine...if you do some research you'll find that hte flange is the problem more so than the muffler.

yes you car reuse the tip's as long as they don't have big giant gob's from welding them on (i painted my muffler with high temp satin black after wards)...they just need to be tacked on. BUT i highly dought that if your exhuast goes you'll by a factory muffler at the price they are chaging for it from hte dealer. for thte same price you can get a s/s Catman cat-back.

here's an idea though...just a though...why not go under the car and see what kind of condition its in?

I have a '02 Max with 103k on the odometer. The flange rusted away on me earlier this summer. Long story short (eBay rear section purchased installed/removed, etc.) I ended up putting a new flange on the OEM muffler, adding 2 new stainless tips and reinstalling it.

The muffler will outlast the flange and I see no near future that my muffler will need replaced, especially since I replaced the flange.

The muffler will last your car, but the flange connected the B-pipe may go. Like the other post said, you can get it welded back for under $50 and you're good for another 100k?

Mine just got loud the other day. Sounds like a race car but I havent had the time to look underneath to see where it rusted through.

Some rust from the inside out. Moisture collects inside the muffler and some have weep holes to allow the water to drain. A good long drive will burn off the water.

All they have to do is take out the section wher the flange is and weld it together. Im having this done on Monday fo 50 bucks. Flange rusted out on the muffler side and the muffler is still good.

For 50 bucks Id rather do that than spend a couple of hundered on a new muffler.
