I picked up my "new" Z on Friday night and was looking at the engine today and I believe it may have aftermarket headers on it. I don't know what the factory headers look like b/c I never paid attention to them on my other Z, but my new Z has got a Nismo exhaust and Nismo CAI and a carbon fiber engine cover, and I noticed today that I don't think the headers are stock either. How do I go about checking to see (I know nothing about headers)! Thanks in advance.

 

Post a picture of the header and the collector.

 

Stupid question...but what is a collector? I'll do the best I can for a pic...any advice, it looks like a tight spot to get a pic.

 

This is the best pic of the headers I can get since my ramps are in B'ham and I can't get up under the car. Any ideas as to what type they might be??

 

Stock headers on a Z could be confused with aftermarket if u were not familiar with them --- They are tubular not cast

 

Those appear to be aftermarket

Stock exhaust manifolds have a silver heat shield that bolts onto them at the top....just off the cylinder head. Aftermarket headers typically do not have this shield anymore.

 

Those look like top speed headers IMO.

 

The collector is the end of the header where the 3 tubes come together.

 

Thanks!
