Muffler small crack - Needs replacement?

[emperorphobos]

Hi there.

 

I have a C4 Cab, 99 with 68000 miles. Yesterday I was under the car and I notice this crack under my passenger-side muffler. Does it need fix (is there any fix on that?) on replacement? Or it's nothing and  I should leave it as it is?

That should not be left as is, both because in many states, you would fail inspection for that, plus it is leaking CO under the car, which can be dangerous, particularly in the winter.

 

Depending upon how solid the surrounding metal is, it could be welded.

Aha, thanks, I passed inspection 3 weeks ago without any issues. I'll weld it thought, in your opinion this will fix it for the next 1-2 years or just temporary and needs replacement? It's on the bottom of the muffler.

That totally depends upon the integrity of the rest of the muffler; if it is otherwise in good shape, it should hold for a long time.

I had a similar crack on both my mufflers (silencers in UK) and decided to replace them with Dansk stainless mufflers at a cost of about £700 for the pair.  It was an easy job, but time consuming as I took off the back shroud.  However, I welded up the seams on the old mufflers and sold them on for about £75 each, which eased the pain slightly. 

 

I checked with my nearest Porsche dealership who quoted £2,600 (including tax) minimum for the work, with the warning that there might be other work that could be needed.
