Couple of weeks ago I modified the NOS (New Old Stock) VW bus muffler with some extra drilled holes inside and welded a extra exhaust port to run dual stock exhaust pipes. I bought a new extra exhaust pipe and cut it in pieces and welded it “flipped” and “mirrored” to fit on right/passangerside of the bus. All this to get a little less back pressure and gain better exhaust flow and still keep the “stock” look, instead of bolting on a extractor pipe. Looks and sounds cool!
