How do you figure? From the picture it obviously eliminates the first cat, but the second cat is far enough behind the oil pan not to burn anything. All the other headers seem to be the same size, and they only remove the first cat.
Check out essential speed they released a picture of there 4-2-1 2pc header. That an interesting design. If it does come with a high flow cat and ceramic coated the price is not bad.

The Essential Speed one uses the stock first cat, not a high flow version.I just find their claims of 20 ft/lbs more of torque a little hard to swallow. It's nice and all, but you still have to push the exhaust gases through the first cat which is restrictive as hell.
Not the shorty header(equal length). They have or will be producing a 4-2-1 2pc header like the racing mazda header. This header will be tested on a car here in florida. It will come coated and a high flow cat.

When will this header be released? Price? Pics? Will this header change the pre-cat to a high-flow cat or will it eliminate it totally like the ractive header.
There is a picture on their web page, it does replace both cats. The header does come with a high flow cat with flex pipe and will bolt directly to the resonator. Price is about $570 (US). Also comes ceramic coated.
