I was wondering if anyone knows of a header that will fit with a Bönez 2.5" SuperFlo System. I purchased a header prior to installation and it didn't fit so I replaced it. I was wondering if any of you have an input? Thanks in advance.

 

ummm. The super flow goes from the manifold to the y pipe doesn't it?

The header would replace the downpipe/presilencer.
Don't know if it still would hook up to the cat.

I have heard nothing but good about Racing beats header.

 

You might be right on that....I'm not sure sure. I will look into that thanks.

 

With the header, there is a 20.5 inch space between the header and the stock y-pipe that you need to fill. Obviously the rb presilencer fits, but other cats might need some custom work. Just buy a high flow and have a muffler shop make it fit.

 

I might try and go measure my cat to see if it is the same length. My silencer/downpipe is pretty long. Hopefully my cat would be the 20.5 like you said.

If it wasn't and you needed to run cats you would have to find a cat with the air pickup for actuation or do the airpump mod.

That's the one thing I don't like about S4's

Has anyone thought about swapping the port actaution system off a S5? Don't know differences so I don't know if it's possible.

Any ideas on this?

 

the airpump mod.

What does that mean I have never heard of that?
I like being able to rempve the air pump in my S4.

 

its Header not Headers.. there is only one.
