Gut Job for Sound Performance...

If you look closely, there is tightly woven steel wool around the primary tube that enters the muffler case. It then travels to the bottom chamber(second internal muffler) that has finer fiberglass packing underneath the chamber which is perforated on the bottom. Both these combos not only reduce sound levels but also reduces any high harmonics(ie raspiness) to the timbre of the sound.

With that said, with the double walled construction, I have yet to see a rust through on the muffler case itself. I've only witnessed rusting on the edge flanges and internal pipes.
Unfortunately no. I hope to get it done by the end of the month as it's looking now(thanks to the house remodel and 3 young kids). However now I have all three setups(factory cats, cat bypass, 200 cell cats) to test the gutted mufflers with to see which sounds the best.

Very interested in the outcome.
I finally got my original mufflers gundo hacked with a 2 inch pipe (screams like a virgin on WOT), and what a difference between the 1.5 inch that I had done on the Gemballa cans. I don't think I will be doing anything more to it other then adding 200 cell cats when my original ones go out.

Technically you are probably right but I think most of us when using the term "stainless", we are thinking 304 and above that doesn't rust as easily.

I welded mine with steel, but knowing that the seams will rust faster.

I have allso some surface rust on my mufflers. The reason why I posted my last post, is that the welder needs to know what the material is. Of course you can weld the cases with steelwire (mig) or steel rod (tig) but the seam will rust faster than rest of the case.
