Is this a stock header?

I bought a modified raptor second hand, I assumed they replaced the whole exhaust system but I'm not totally sure. I'm just wondering if anyone can verify if this is the stock headers that got a slip on put on there? My raptor is an 04

I dont think its OEM. The stock header has nuts welded on it to bolt on a heat shield. OEM also does not have the springs holding it together

Agreed with above. That is a pro circuit header. Congrats you have a full system!

You can see the spring retainers/springs and the thick header flange where it meets the head, identical to yours.
