So I just bought a ZZP shorty header and ZZP 2.5 downpipe catted downpipe used and the header isnt branded but downpipe is. They are older and apparently bought new in 2015 so i just want to know if they are authentic. I'm skeptical because the manifold flange or whatever isn't even the same but I saw a post on here of someone selling a zzp one that looked the same and wasnt branded.

 

id say its more than likely a zzp header. i did see some pictures of the zzp short from about 5 years ago that have that style header to head flange. zzp is also the only shorty header i can find for these cars with the center 2 primary tubes going to the top of the collector.

 

So I purchased the same exact shorty header brand new from Zzp & this is what mine looked like while still in the box, mine says Zzp on it
