1 Answered question

Does this converter have the flange on one end to bolt up to the manifold as shown in the picture? I am only finding cut and replace converters so I want to make sure?

Asked by Bob from Kirkville, NY on

Bob, the Flowmaster Exhaust Direct Fit Catalytic Converter is made to be a direct replacement for a 97-98 Tj with a 2.5L motor. So, as long that's the Jeep you have then it will be a direct bolt on for you. Thanks a lot!
