Seems like everyone just go grabs a Racing Beat header. Did anyone try and look for another brand? because the Racing beat headers don't seem like they're that effective.

RB headers have 30 years of development behind them, I'm pretty damn sure they're effective.

I have an RB setup on my FB and an RB downpipe on my TII

 

RB headers are dyno proven to add alot of horsies. I know because I have them on my car. They made a BIG difference. If thats not effective then I dont know what effective is.

 

There are 3 brands of N/A headers that will fit. Obviously Racing Beat, another company called Mindtrain, and Pacesetter. Mindtrain headers I believe will bolt to the stock cats and are pretty high quality, similar to the Racing Beat. I think they are a little more expensive.

Don't even give Pacesetter the time of day. The are crap. They don't fit well and the pipes have walls that are too narrow.

I have the racing beat header on my car and love it. I know someone who has the mindtrain on his car and he loves it. Depends on the how you want you system set up.

They are very effective. However, if you don't like them, then just go grab a Racing Beat exhaust flange and make your own headers.

 

RB headers kick A##! they made my rex quicker

 

I understand they will give you a significant gain over stock, but how about against other brand headers such as hytech, smsp.

I've not heard of Hytech or Smsp. Do they make parts for RX-7s?

O.k. I know... I should know better.

Headers: The pipe in front of the downpipe? Attaches directly to the block?

I have the bonez Superflo. Anyone know a header that'll bolt directly up to this?

Thanks.

 

Racing Beat is the best way to go period. We even use their header plates to make custom Turbo Manifolds.

 

The owner of Mindtrain saids a header would only add 2hp over the stock cast iron manifold, and it was dyno on their series 4 test engine. He saids that we feel more power only because a header would bump up the torque curve considerably. And torque is what really gets you going, like those potent V8 off the line. High hp # is mostly a result of better flow, elimination of cats, and stock mufflers. The part I was sold on was that his headers were claim to be equal lengths whereas RB is not. And that RB header tends to lean on the front rotors. He saids if the current owners of RB headers were to take out their header, they would see different shades of color b/w the f and r rotors, indicating a lean condition. The butt dyno b/w the mazdatrix true dual and Mindtrain's setup I had at the time was very little difference, surely not worth the almost $800 difference.

 

Since when are Racing Beat headers NOT equal length? I have the RB duak outlet headers, the the pipes ARE the same length.

 

Nope, headers have longer runners than the stock manifold, thats partially why you get more power put of them. Your bones superflow will not bolt up to any headers. You can get headers, and have a shop cut and reweld on the flange on your superflow though to shorten it to match up with any headers.

 

dude, just go grab a Racing Beat header !

 

Ok, so if i get the RB header should i be worried about the 6-ports not opening if the rest of the exhaust remains stock?

 

don't worry, if they open now, they'll open then.

 

Remember who your talking to kim. A salesman. I talked to a pacesetter company and actually had headers and catback on order. I was convined. Mindtrain header guy says something about lean? So ok. Big deal. As for length, Yes they may be different but for a reason. Its not a flaw. Mabey one is longer even out the flow due to one curving more. Or I think the one with the oxy sens on the single is the streighter longer one to make up for the flow of the oxy. Just a thought that I dont think u should stress on...and go grab yourself some rb headers.

Hey mazdaspeed7.. Why were unhappy with your duall. Doesent it gve better top end and torque...

 

As for those 2 brands are concerned, those are really coveted within Honda/Acura market because they result in 20hp gain to the WHEEL!!!!!

Anyways....I'm asking hytech if they could design a header for 13b 6-port. They design headers for F-1 Formula cars.

I'm thinking of using the RB Road Race headers with 2 2" oulets and use 2 RB presilencers and 2 Borla XR-1 2 1/2" in/outlet. And just 2 1/2" piping in between. What ya think?

If what Mindtrain claims is true about RB single collector headers leaning on the front rotor, I think it's a big deal. Afterall, the stock TII motor setup tend to lean on the rear rotor(of course not from pipe length differences) from fuel starvation. But lean is lean and is BAD for the motor; Back in the days I spent over $500 for the Mindtrain single collector header to their high flow cat and then switched to the $1400 Mazdatrix dual exhaust setup; guess what, I was NOT Impressed and plain disappointed, and so is Mazdaspeed7 with dual setups. Gains were minimal. Mind you, this is my 5th NA RX7; perhaps it's time for a change.

 

Ok when an engine "goes" which rotor fails most of the time? If you know the answer, thanks

 

On an N/A u fail becuase of something went wrong and the leaning out was icing on the cake that toped it off. My car is well tuned so I can run lean for the life of it.... One time I drove with the ACV plate completly off and had a huge intake leak. I did this for about 600 miles untill I fixed it... Thats when I was just getting to know rotories. I even raced it like that and beat a CRX. I was mass lean and had the timing bumped as well. My engine purs, or did before I cloged the injectors. But the N/A is way more forgiving than the turbos like u know, but u dont relize that leaning out with the RB header is probly no big deal... But what do I know. If your worried get a t11 fuel pump and afc. That should give the first rotor the gas it needs.

 

My RB header on the first gen is the same discolored shade of blue on both tubes. That Mindtrain guy is full of ****.

 

Thank U

 

**** it and go grab some RB headers.
