So I finally installed the high-flow cats which I ordered alongside replacing the H pipe with an x pipe.
The high flow cats are 50 cell . And damn am I happy with it . The car is much louder now . I would say at least 30-50% . Which is exactly why I did this . The sound of the exhaust has also changed. The car just sounds pure mean now . It does have a gas smell at idle. But its not overwhelming. Overall , super happy I did it . So high flow cats , defiantly raise volume and change up the sound .

Might be a dumb question but did you need/have to tune your car for the high flows? Or everything fine?

It only had to be welded on one manifold correct?
