Magnaflow 49 State Direct Fit Catalytic Converter Reviews
I’ve had mine on for many years , still great , more flow than oem , I paired mine with the banks header and banks catback , I would def reccomend
Fit like OEM but catalytic converter was much smaller than OEM and appears to have better flow than OEM. Restored my muffler system to better than OEM.
Have not installed yet, but like the Stainless steel option. Better life, and it comes with the mid pipe. Would prefered 304, and willing to pay a little more for it if it was 304 stainless.
