anyone know the dimensions for the inlet and outlet on the stock muffler for a '98 lesabre custom? im looking for a new muffler and i was hoping to forgo crawling under and measuring by hand

im fairly certain it is offset 2.5 inlet, center 2.5 outlet

would appreciate any input

thanks

I think it's a 2.25 actually, but It may not be. Mine was originally that size.
