Any track visits after the mods ? Front mount air filters ? No codes after secondary cat delete ?

Yes I go to the track pretty much every weekend. It was very minimal difference on times at the most maybe shed a 10th. There was no codes and it was not front mount. It was a ghetto setup I made, you can see them . I however have since 3d printed some front mount ones and now wrapping in carbon fiber but have not put it back on the dyno cause doubt it made much of a difference.

I would not call that ghetto. Nice setup from scratch.
