1934-1954 Pontiac Factory Correct Replacement Stock Exhaust Muffler

Stock replacement muffler for 1934-1954 Pontiacs. Please match specs to your pipes prior to purchasing to ensure proper fitment (including whether the front of the tail pipe is 1.75" OD or expanded to ID)

With a 409 stainless steel shell, this muffler has a 5 inch round body with dual baffles and a center/center inlet and outlet positions. It has a 35" body and is 39" overall in length with a 2" ID inlet that will slide over the head pipe and a 1.75 ID outlet that the tailpipe will slide into. Please ensure these specs match your application as muffler shops over the years could have modified the pipes if not original. If your tail has been expanded to slide over the outlet of the muffler, please specify in the notes when purchasing.
