Check out my muffler. Is this outer sheet metal wrap with the very lumber banding looking straps stock?? If its not that sure would explain the slight leak... I hope its not stock thats a pretty piss poor design if it is.

That looks stock, but maybe damaged or repaired somewhere along the way. Looks like it is not a cleanly wrapped on the ends as it should be.

The skin you are looking at is just a heat shield of sorts ... under it is an insulating mat and then the whole muffler inside ...

Stock. Given that this poor design has lasted as much as 36 years already (first underhood mufflers in late '76, and I have found them to be in pretty good shape even that old), I bet you peel off the "insulating tin" and you find an easily repairable muffler underneath.

Just Re-crimp any leaking ends, re-wrap and perhaps go another 10-20 years ?
