anybody have any info on OBX headers?
never really saw anything on the forum, searched, still didnt find much

their about the same price as pacesetters. wanted to know if theres much difference..they look the same too


btw 1)not really interested in rb's. too much $ so dont suggest them
2) if u got any headers for sale lemme kno

 

Check out the Corksport header, they sell it for a resonable price and they said they dynoed like a 14hp increase or somethin like that on a turbo.

I can't quite remember if im right or not but just check they're site its all on there.

 

basically your asking us which piece of crap is better. neither save the money buy racing beat. i wouldn't be surprised if obx or pacesetter didn't rust out on you in a couple years being on the east coast.

 

yeah but its like $300

Looks like OBX decided to copy the POS pacesetter header.

DAMN CHINESE!

If your gonna copy something, why not copy the best?

 

The RB headers cost as low as $220 (plus shipping, not sure how much that are). There's a reason they're more expensive, IMO.

 

Or better yet save the money for a TII swap.

Or a bridge/p-port.

 

yea but they also dont bolt up to stock locations right?
dont u also have to buy the other piece along with it

 

Need header + pre-silencer combo.

 

Corksport makes turbo headers?????

 

Apparently. I'd like to see a turbo header myself, I'm curious how that works.

As for OBX, they look like another cheap-*** company. Let me tell you something about the rotary engine: it has INCREDIBLY hot exhaust. Low cost exhaust systems like this use thin, low-quality metals that will warp due to the extreme heat of a rotary engine. I have personally witnessed this. When I bought my car, it had a bonez mid-pipe, and the flange was noticeably warped due to heat, causing a non-fixable exhaust leak. A similar thing would happen with a header of this quality.

The RB header/presilencer now costs about 550 + shipping, which is a bit expensive if on a budget, but is perfect if you want to get rid of the cat. The corksport header is only 300+shipping, so if you want to keep the cat its more economical.

 

I think he meant dyno???

 

Really? I thought the header would bolt up to the main cat (eliminating the pre-cats). I thought pre-silencer would eliminate the main cat.

 

Well from the racingbeat website:

Our Streetable Header/Collector is designed for a bolt-on installation, when used with the appropriate Power Pulse Presilencer, in all 1986-92 non-turbo RX-7s. The combination of this Header/Collector and the appropriate presilencer replaces the stock exhaust manifold and all catalytic converters, along with any intermediate pieces of tubing. (In this application, the presilencer will bolt-up to the factory Y-pipe.)

For optimum performance gains for this application, we recommend that a header be used on an engine configured with a carburetor intake system. For this reason, we suggest another suitable configuration for use on a fuel-injected engine is the Racing Beat Catalytic Converter Replacement Pipe with Presilencer combo. These components offer comparable performance gains, quieter performance and a price advantage as compared with the header/presilencer combination. These components replace only the stock exhaust components located between the stock exhaust manifold and the Y-pipe.

I believe the header replaces the exhaust manifold and pre-cats, then the presilencer replaces the main cat. However you cannot hook up the RB Header to a stock main cat.

rx7.com sells rb header + high flo cat packages that bolt up to stock y pipe. And High flo at that bolts up to y pipe and rb header.

 

I say go for it and be our guinea pig. It says it's made from stainless, so it should stand up to the heat. Or you could wait and try to find a used RB or CS for sale.

 

For $50 more then that OBX knockoff of an even crappier Pacesetter header, you can have an equal length stainless header from Corksport, or Mazda Motorsports, etc.
