Hi guys. I tried doing some reading on previous posts but couldn’t find what I was looking for.
I have a 2018 Cummins. I ordered a 4” exhaust and when It got to my house I opened the box and realized it’s not turbo back, it’s a down pipe back so basically what I am trying to figure out is if there is a CAT on the factory down pipe or is that a flex joint I see? If it is a flex joint I plan on using what I have but if it’s a cat I’m gona try to buy turbo back because I would like everything deleted. Thanks and sorry if that is confusing!!
