I've already searched, to no avail though because the search function BLOWS... but anyways, I'm wondering if the streetable RB header has a bung for the 02 sensor or are you actually required to get the presilencer as well. All the pics look like there is no bung, but alot of places use the same pic for all similar products and this could possibly be a pic of the race header. Any help would be appreciated because I need to know how many billions of $$$ I'm about to spend on my new exhaust setup. Thanks.

IIRC i think they have two different types of headers. one for the s4 and s5. i'm a noob so i don't know which is for which version.

 

the streetable header.
i think thats the one i use to have
it looks just like the one in the pictures
and yes it had a bunge for the O2 sensor

i also had the presilencer
and there was no O2 bunge on the presilencer

 

The presilencers USED to come with the air pump inlet, but RB has since gotten rid of that. Anyways, thank you very much for the info guys

 

You're talking about the split air tube.

That's more for series 4, where you need the backpressure to actuate the 5th and 6th ports. The difference between the s4 and s5 presilencers is that the s5 doesn't have it, since it's not needed.

I haven't checked lately, but I'm sure they still come with the split air tube connection.

 

^Ah okay. Well, I guess I don't really need it since I'm S5. I'll probably fab a blockoff plate for that at the airpump.
