The existing internals (sheetmetal walls with multiple holes)of an original muffler are removed. Only 1 similar sheetmetal piece with holes in a rolled form connecting the inlet to the outlet of the muffler box & stuffing fibreglass wool in the now empty box before welding it back.
My known term is called "operating the muffler". Will doing this cause any of the check lights issue? Is the exhaust air now more dirty that a stain will be left on all light colour cars?
Many thanks on any help/suggestions.
