Interesting about the leak at the cat. I have a similar issue with mine when driving on the freeway between 50-60. All I’ve found on the forums are that it’s an injector issue. So I was going to send them to whichhunter performance for them to clean up and rebuild.
Does yours act like this? Small video I took of the rpms fluctuating.
