do I have after market headers

[skatr]

I know this may sound like a stupid question, but I am not 100% sure that I have aftermarket headers. Is there any easy way to tell by simply looking under the hood to see if the headers are aftermarket or not?

are they round and smooth or are they squared and rough?

can you provide a picture?

Yes, if your exhaust manifolds are 3 big tubes then they are. If not that will be ugly cast iron logs. If you still aren't sure, take a pic and we'll teel ya. And if you can't see the exhaust manifolds because of heat shield then they are stock because the heat shields won't fit over the headers.
