I was browsing RB's website because I'm going the N/A route and wanted a good header, but they have four different RB headers!
I don't know which one is best for me
Do these bolt up to the stock exhoaust? And while we're at it... What better the CorckSport 13b Header or the Racing Beat 13b header? Thanks guys

is your car an s4 or s5? if s4.you need to decide whether you wanna keep your aux port actuators or just wire the ports open.
Then , if you DONT want the aux ports
decide if you wanna buy the big $ true dual system cuz unless you buy everything from racing beat it wont bolt up to anything else.!
if you dont like noise buy the straight pipe/presilencer combo they sell, headers are QUite Loud!

I have an S4 
I would like I thought the RB design meant the actuators (still don't know what those are) would open at the right back pressure. I would like something with an O2 bung so I can still pass the emissions tail pipe test. I imagine noise shouldn't be a big deal if I just shift at lower RPM's during daily driving.
BTW how big is the stock cat? 2.5 or 2.25 I'll replace it with a high flow unit while I'm at it. I'm sure a new cat will clean the air bette the 20 year old stock peice anyways.
Anyone know about Corksport?

the problem with getting a new converter is that you will have to get one custom made or buy a rather pricey bolt up one from Mazdatrix.
the reason why: FC headers are NOT meant to bolt up to stock #3 converter. so........
go to mazdatrix.com or you could just get a bolt up pipe off of ebay can be found for 35 bucks however if you just bolt up a pipe and no converter you will Never in your wildess dreams pass emissions
@ mazdatrix they sell all the racingbeat stuff anyways but also have the matching converter if you desire, RB only sells the matching presilencer no converters.

http://mazdatrix.com/e-gray.htm there ya go
but after reveiewing the mazdatrix page myself they sell RB headers but only list one for ALL 86-91's so they dont stock the one you need (with the tube for the ports). maybe call em up or something, they DO have the bolt up converter though and it aint cheap.
and i HIGHLY suggest you find video clips of a FC w/ headers to make sure you can stand the noise, trust me, shifting at lower points aint gonna do squat it is LOUD at startup at idle ALL the TIME! (with a straight pipe like ive been running on my fc)

racing beats presilencers are the **** when it comes to sound...BUT i will say i've purchased two for various projects and ive had to pull both back off before. and i had one to two studs break upon removal with both different units. bolts were not hot AND i sprayed them with liquid torch (penetrating shiat that always works for me except for here). anyway they weld the studs into there presilencers so you cant ******* replace the studs. bastards.

My FC currently passes emission no problem what so ever right now, I'm well within legal limits for nox, co2 etc. The engine runs great! I don't see why a header would make me fail...?
Unless I'm removing cats by installing a header? I thought the S4 only had one cat?!?

stock s4's come with 3 cats.\,. installing a header replaces the front 2 and like i said the last will not fit anymore due to header lengths... so.... you can always just keep your stock cats and some spare gaskets handy and just install/uninstall for emissions test and put back on your headers after the test!

Damn! In that case i might go with a Random Technology Catalytic Convertor + a Cork sport header. The RT cat should bolt up as should the CS header. RT's cat should (in theory) do the work of 20 year old cats.
