I have a tiny bit of melting on the bottom of the shroud.

Do you guys have your header coated? Thinking this might be the way to go with some gold tape on the intake box.

Yes, mine is ceramic coated. I think on the street I wouldn’t have an issue. It is sustained high temps from track use. I have everything foil taped that the tape will reasonably stick to. Intake, wiring, hoses.

I heat wrapped the entire manifold before install and I have yet to have any issues - also did the heat tape on the bottom of intake box.

Got mine ceramic coated from the start. No issues going on 6 years now.

There was a small amount of plastic that melted on the fan shroud but that hasn't caused an issue. Also from track driving not street driving.

I have a Nameless I want to run on my 2022! Anyone Else?
 

I'm talking to my tuner about tuning my car once I've installed the long tube header and . Has anyone done this yet with any of the long tube headers? Anyone keeping a CAT or using a high-performance aftermarket CAT? Mine came to me with a CAT at the very end of the overpipe.
Performance gains?

The header itself is catless. What has the cat is that front pipe set up; which looks like the JDL overpipe/front pipe combo they did for a while. The cat or no cat makes minimal difference and mostly helps for noise and rasp. I ran those headers with a catted front pipe and had no issues. Tuning was done by Cosworth at the time though and it was a solid set up. They do have a lot of rasp though, just a heads up.

I have no rasp with my nameless setup.

Really? I had a lot of rasp!

I think it was HKS that first offered a catted front pipe with a bung and extension for relocating the secondary o2 sensor. Now I can only find this.

Yup. Catted and resonated front pipe, stock midpipe, ultra quiet track pipe. It's really not even that loud.

Yep, they still do. I actually went the full length to acquire that front pipe a few years ago. It comes with their catless header and a catted and muffled front pipe that has an O2 sensor extension and tap. Absolutely not worth the money if you're anything less than a parts snob like myself.

I'd say if it legitimately doesn't throw a p0420, then it would be worth the peace of mind to know that I'm not being a complete NOx-rolling asshole. Maybe not as good as full stock, but still above the alarm threshold, FWIW. That's the only way I would do an aftermarket header.

Yes. Besides the corrosion resistance and resistance to high temps, parts can be made thinner and thus lighter. I made a twin scroll up pipe for my 470 HP STI out of .031" 321. It has been perfect for years of track days.
It must be welded properly with back-purging. Takes a decent TIG welder to work with it.
