@creamqueen If you don't have to pass emissions, you can wire an old steel can around it to keep it from blowing exhaust at other components.
@creamqueen Is that white scale salt residue? Even stainless steel will rust at the welds because the heat from welding blasts the chromium out of the alloy. A high-temp paint on the next pipe may prevent this from happening again, but they don't salt the roads where I'm at so I've never had to try paints.
@creamqueen Got a warranty on it? Also suspicious that all the paint burned off. Doesn't look like high temperature paint was used.
@creamqueen for the expansion chamber, at least.
