Like already mentioned, these aftermarket Subaru exhaust systems are relatively easy for any company to pump out.

It's not a complex problem,.

There are many resonators and universal mufflers one can buy and experiment with.

The concept is relatively simple to me,
I hate to sound cliché, but if it's so easy, why doesn't one exist? We gave it a shot, and I'd like to think we've got some decent knowledge with these engines, turbos, and the science behind the exhaust system.

It's hard not to beat the very inefficient OEM manifold. I saw one made from galvanized tube with bubble gum welds perform better than OEM. My point being, if you're shooting for better than OEM, it's not hard to do.

We on the other hand we shooting for the fence, and I think we can confidently say our header is the highest power producing header you can get for a Subaru; based on shop independent and customers doing their own testing and comparisons. Our customers are not the budget minded, but those looking for no compromise quality and performance.

Absolutely. If you make a pile of poo sound good, people would buy it... because it's good poo, it's what the internet said

Special order? We order them just like the older Gen I

How long to you project that gasket will last?

What type of material is it, if you don't mind the question?
This gasket was used on the first 5 or so kits IIRC. It was CGM and lasted... well I've never seen one needing to be replaced and they are reusable. Fortunately, we made some subtle tweaks so no gasket is necessary.

General.
