Hey there bro!

I am not sure I wanna go for cats right now, I aint touching anything that has a sensor in it!

If i'm not mistaken, these headers will also replace the secondary cats.

I am still confused as to what exactly people around here refer to section 1 and 2 in translation to Primary and secondary cats!

I belive secondary cats are immediately after the headers, and then come the primary cats, then the xipie (resonator) and then the mufflers!

COrrect me if I'm wrong!

Which cats are these that you are reffering to?

The primary cats are attached to the stock headers. When you replace it with an aftermarket unit like the Evosport one, then you're taking out the primary cats with the stock headers. What you have left is the secondary cats (Section 1). Lots of people replace this with either high flow cats or straight pipes. The Evosport high flow cats I mentioned would be the replacements for these secondary cats. The next section with the X-pipe is the Section 2 and then the rear mufflers are Section 3s.

Aha.. thanks bro!

I will obviously need an ECU upgrade to knock that CEL off the screen!

Unfortunately, his cats were sold!
