Ok so I still don't know what to do With headers. I feel like a complete idiot because I keep asking but Idk what to choose. Every header choice it seems like does not come with a catted DP. Even zzp on there website says nothing about coming with a catted down pipe. TOG. Extra 320 on top of 789 for headers. I want headers that will be Legal in the state of Missouri. I need cats. But I'm not trying to break the bank. But seems like every header choice I have has something wrong or something else u need to buy that's pricey
