Ok, next thurs, imma get a zzp header with a catted vibrant dp. I noticed that zzp's header has the o2 sensor connection where the 1st 2 pipes meet. Wont this give a bad reading?

Also, will the zzp header bolt up to the stock dp and the vibrant dp?

BTW, the vibrant dp is 2.5" (Perfect, cuz my catback is too)

Thanks
