I have a burnedout RB SP header I want to replace. Its not repairable or I would have
it welded up.

I know that pacesetters exist and are crap. I know some vendors have headers but
not for 12As. I did find these guys on egay:

(if the forum eats this url because its egay I can PM it to anyone interested)

Anyone tried these? Are they dimensionally equal to the RB SP header?

 

I'd spend the $74 more and get a header I know will fit. Or I'd see about repairing yours. I've done it before. The header had a dime size chunk missing in the same area. Caused by bad timing. The tune also wasn't very good from a dellorto.

 

I've heard good things about cxracing from the 240 world. Some people say their products looks like any other ebay part but people who have ordered from them mostly had good words. I don't know if I would go for it though. $200 is steep for something you don't know for sure how it is.

 

Cxracing and rotary-works same company..never tried the headers but have bought a lot of other parts from them.local to me about 15 min drive.

 

Stainless steel for the CX, might sound tinny and look shitty.

Heavy duty soft iron coated with a pretty chrome finish for the RB, sweet sound, sweet look.

No contest for me, RB all the way.

 

I've seen and thought about those headers as well but I'd rather just spend a little more and go racing beat

 

For $150 you could get the racing beat disassembled road racing header for a 12a

 

I could but I don't have a welder or skillz for welding, so I think I'll pass.

Like Ray said there is something to said for getting new shiny bits in the post from RB. I may just do
that. I did some research on CXRacing and I'm not sure if that header would work plus as Ray
pointed out it is SS, which may make a racket.

 

I agree. RB's tubing is thickwall mild steel (it's not iron, Ray!) and can handle the supersonic pulses as they exit the ports better than most other materials. Plus you know it will all bolt up together correctly. I think the peace of mind is worth the extra bit over the questionable cxracing header.

 

If you cant find a used Rb 12-a header, get a 13-b header and cut the engine flange. Otherwise, lmk and i will ask my friends

 

"thickwall mild steel"

Thanks Jeff, I knew it was something like that.

"Heavy duty soft iron coated with a pretty chrome finish" is the impression I got when I unpacked mine from the shipping box.

Those RB headers sure are well made and pretty to look at.

 

Correct. Think mandrel bent steel tubing. I don't think iron pipe can be bent at all because it will simply break. You also can't weld iron very easily with a basic MIG.

 

Ordered header now the waiting starts

 

To whet your appetite Tim, here's what they look like when they come in the mail, Christmas in August for sure:

 

Shiny parts! t_g will discover he will want to pop his hood a lot more now to show off the shininess!

 

For those that live in salt-free environments, chromed steel may be a good alternative; for those of us who live in the rust belt, it doesn't last very well. I'm not bashing the RB header -- as a matter of fact I just bought one. But I know it will look like crap in a year, and eventually fail. I previously had a street port system on a 13B, and the muffler was showing signs of structural failure after 4 or 5 years in the salt. The OEMs all went to stainless because the regulations forced them to provide reliable emissions equipment, and mild steel couldn't do it, no matter what they coated it with.

A good stainless header would be a nice thing to have. BTW -- RB's latest shipment of muffler sections is stainless. I'm guessing they get them from overseas now and can get stainless for a reasonable price. All the pieces will probably migrate to stainless over time. The deciding factor for me was noise. I want the car I'm building to be quiet, and I couldn't find a full stainless single pipe system.

 

we have one of these on my cousins car, best header you can buy! all stainless, purpose built merge collector, and the famous crossover tube

 

Those are nice and everything but they lack a cover over the thermal reactor air injection holes found on all SA engines. They're probably all built with a 13B flange only. They also collect early.

I prefer long primary type headers because I like the enhanced power everywhere in the RPM range. Not just enhanced high end like those stainless collected headers can do, regardless of the crossover tube.

 

Header is supposed to be here today via UPS but the truck from MS to GA was late into Atlanta, so
Christmas may be delayed. They haven't reposted a delivery date yet when I check the tracking

 

At least UPS is better than ontrack. Try waiting patiently for a package from them.
