Same thing can be said on my brothers ZL1. Catless headers -> stock suitcase = shit. Catless headers -> resonated X -> stock suit case = Good!!

That being said I do get a few burbles and crackles on decel but it's not anything crazy or else I would tune it out.
So my setup isn't catless, they are ultra flow cats so might be close to catless? Also, trust me, if I knew how to turn the burbles and crackles OFF, I would !!!!
