I'm talking SC not turbo. I know the drawbacks of going turbo, which is why I'm interested in SC. There is a very huge difference in EGTs between the two. Also, 200 cell metallic core cats aren't that expensive.
I have no idea why everyone thinks this. It's been a long time since I looked into cat prices but they are still the same. Around $100 for a magnaflow 200 cell metallic core. I'm starting to change my mind on how this header R&D is being approached if you aren't willing to test this before release.
Just an example:

Also Miata guys have been running PPI catted headers on SC'd cars to fix issues with not running cats causing CELs. So please don't tell me this isn't possible. Please read this thread to see what I'm talking about.

I just don't want to see our best shot at a great header for a great price lost because of a lack of vision or willingness to do the necessary R&D. Not trying to hate on you guys, but there is a market for SC guys and catted headers.
