Gutted or not hfc

That's not an HFC. If you could put a stick through the pipe, it's not an HFC. HFC will either look like the pic shown or have a spun metallic core (looks almost like a loose roll of foil). But there will always be a core of some kind. Those aren't gutted either, as the other posters mentioned, it's a resonated test pipe. The holes are part of the sound suppression.

You can't tell from the outside since a resonator and hfc shell look about the same. But the inside of yours shows a resonator. HFC inside should look like this (not my pic, but my Berk HFC looks the same). See how there is material there, that's the catalyst. If you don't have it, it's not an HFC. And yours isn't technically "gutted" either. Gutted implies that you took an HFC and knocked the core out which people do if it fails. Yours is a resonated test pipe. If you don't have to worry about emissions in your area, run it.

https://g35driver.com/forums/engine-...est-pipes.html Says at first they are test pipes then a user posts two pictures of the hfc and test pipes then says based on pics they are hfc along with other users, this shouldn't be my fault but there's nothing I can do, at least I get more gains

Its not your fault, the seller is an idiot for not knowing what he had and falsely advertised. If he's not willing to do anything then he's a POS and should be banned. I'm assuming you bought these before October 23'rd since thats when the truth came out in the FS thread.
