Default 2.5rs header on 04 legacy

Does anyone know if you buy a borla style header for a 2.5rs if you could put it on an automatic 04 legacy. I know the 03+ auto legacy had a different design in exhaust wonder if this will work with custom high flow cat from header to the exhaust

Looks exactly like the h6 manifolds but its a ej259 with 4eat has total of 5 o2 sensors and three cats and its definitely holding the car back in every way power and MPG

Uel headers actually are less efficient

No way they are less efficient than having three cats on there.

The cats do take away but I'm saying el vs. Uel, the equal length will be able to get more power

You could always take some of them out

Yea I was just doing some more research online and turns out the 04 started the pzev engine which is terrible to mod and makes no power. Super disappointed
