Sorry, but my english is bad. I want to upgrade all my exhaust pipe or catback, I don't know the correct name. I want to upgrade +1/4" and delete cat and the pre muffler. Anybody knows what is the OEM width or diameter for a versa 1G 1.8 MR18DE? I hope I could explain me correctly. Thanks! It should be 2" OEM. I know mines is 2" OEM and its a 1.6L.
