It says that you cannot use the stock headers, is that correct? Wouldn't the cost skyrocket then?

Yeah.

So, on one car I have stock headers, ess hfc xpipe and an evolve valvetronic exhaust.

On the other... that's the matter for another discussion... and another DIY

Fully catless and don't look back.
You won't regret it...people over exaggerate the smell.

I don't know how you can bear it.

With HFC, it still smells bad if the car is on and you're around the exhaust. I could never do catless... besides the illegal aspect of it

How can you not like the smell of raw fuel!+orgasmic exhaust note
I barely smell it and it's only noticeable when I come to a stop.

I do feel bad for the electric cars that go behind me

I'm definitely with you regarding the exhaust note! And I like the smell of gasoline, just not after its gone through an engine
