A catted aftermarket header is just as illegal for carb as no cat at all. A catted header is more expensive to manufacture and can't be ceramic coated on the inside A Catted header is generally believed to produce less performance gains. All of these reasons are powerful disincentives to develop and produce catted aftermarket headers.

At the end of the day a customer has to look at a company's customer service reputation, quality, design, performance and plug-n-play capability. I knew I wanted a catted header to pass visual inspection (the rest is more a wave of the hand if you know the right people...). I also chose UEL since I felt it better fit the platform, sound, and general upgrade path I have planned (no forced induction). FT-86SpeedFactory has created a header that can work bolted on, with or without a tune. So for those looking to take one step at a time, it is ideal (tune later).

So you ran lean and melted it or to rich and burned it up...........I wonder where the fault is at, the header or lack of / bad tune? My Catted header works just fine, but it is an equal length header as I want performance over sound.

If your going supercharger, Don't even worry about a header. Its a waste of money. Stick with stock. I rather dump money into a flex flue kit (if you have E85) which will net you way more power then a header.

Because a cat that close to your engine block is robbing you of easy power.

let's review 1 it is illegal to replace a catalytic converter unless it is defective that is federal law. 2 switching out to a header with a catalytic converter does nothing for power. so therefore 3 you're wasting your money go catless or don't go at all.

It is most certainly not a waste of money. If I did any type of FI, the first thing I would change is the header.

Well then you have looked at many dyno's have you The headers do not add much on the supercharger side. Like I said Flex Fuel would be a much wiser choice
