So I’ve found soo many videos of every available option, yet not every variable. What I was looking for was the secondary cat delete at idle after cold start. But, I think I’m going to go full high flow down pipes to add to my g exhaust h pipe. Anyone that would like to hear that feel free to shoot me a dm on insta jmort443. I feel when I first had it put on it was almost zero difference. But after a few hundred miles and break in I had a friend ride with and say it sounds a good bit better. I believe with break in it slowly sounded better so that’s why I don’t notice much.

Long story long. I’d like to have someone with high flow cats shoot me a video of it at idle after cold start and also with valves closed before I pull the trigger.
