Took car over to the place sline recommended for ceramic coating this am. Going to have the muffler parts done.
They want to know if the muffler chambers-I think there are two- have asbestoes inside.
Said it could melt...

Anyone know whats inside ?

I think mine gots rattely plates inside. IDONNO about any fibers.

Just call the mfg. of Bursch / Horsepower Engr'g and ask them: 626-440-0440.
FWIW, proll'y only chambers in the muffler cans

Thanks for the number; I'll call this am

BTW, I mentioned to the owner (Bursch) that his shiny black paint is worthless as it is NOT heat resistant. Furthermore when I resold one of his 924 headers (we mfg. our own since then), the paint actually ignited in a customers car. I was kind enough to bring this up to them...they told me I was blowing smoke !
The mufflers that they use on their systems are the cheapest Walker turbo units money can buy. Yesteryear technology at best.

I'm thinking of the Dynomax Bullet in place of the Bursch Muffler. I'll have to get some size adapters. smallest they make is 2 1/2".
