I was looking at the store that you can access from this site. They sell a mindtrain stage IV street header for 81-85 rx-7 for $159. They also sell racing beat but have no listing for an 85. How does the mindtrain header compaire to the racing beat streetable header/collector. It is a little cheaper. (also my budding is ordering a precilencer for an 87 and it is $10 cheaper on this site as well (we can split the shipping)) I know you guys talk highly about racing beat, but I have not heard much about mindtrain. Can you tell me the differences (ie. power wise, construction, does it bolt to the main cat (although I have a straight pipe).
Thanks

 

Mindtrain products will bolt right up to the factory flange and the RB won't. Also, the owner of mindtrain had some good points about the construction of their header versus that of the RB but everyone is going to talk up their product a little. The guy did seem very honest and straight up about it though. You can build a mindtrain system piece by piece where as you'd really have to almost buy a complete RB system to use it (unless you want to make multiple trips to the muffler shop). I would say it all depends on what you're after. The RB dual pipe system is really cool but If you want to use some of the OE single pipe components, I'd go with mindtrain. Ok, I'm done.

So it is 200 for that header anyone find any better prices?? For the midtrain 12a.

 

i have the Road Racing Headers from RB... it is a dual pipe system (in fact, i bought the entire street port system from RB and i love it) so it won't bolt on to any OE parts...

ALTHOUGH... RB does make some headers that converge into a singe pipe, which MIGHT fit on the stock cat... (i'm not sure though)
E-mail them or call, they seem happy to help (especially since they charge so much... but maybe it's worth it )

 

anyone heard of bonez headers I was thinking of trying them i can get them locally and local means faster. but what is a good header if you are doing peice by peice the rb is out of the question just will not bolt up easily until i can but the rest of it.

ok mike jumped the gun a little(bitch slap). the m.t. stage V stuff will bolt up to the stock pipes but not all of the m.t. stuff will. The R.B. stuff is NOT a bolt up to stock pipes kinda thing. I had the full stage 5 from m.t. and LOVED it it was loud but it was worth it......the flames and looks i got now im running the stage 5 header(with o2) and a bonez high flow cat, all bolted right up with no probs. I guess the only thing i wish m.t. would do is the plating that r.b. does. they come with good high temp coating but after 2 years it is wearing off. the r.b. stuff still looks good after a few years. thats my only complant.

 

I got an email from racing beat. You are right. The streetable header collecter also replaces the main cat. Thus a presilencer or custom pipe must be used to connect it to the stock pipe.

 

this still does not seem right. if the header replaces all 3 converters that is one long header. Do you think the guy at racing beat made an error (or does he want me to buy his presilencer?
Can someone with the steetable racing beat header/collector please verify this.

Here is the answer he sent me.
The header will not bolt-up to the main cat, but replaces it. To make a
connection to the stock connecting pipe, you need either a RB presilencer or
a piece of custom tubing (this will be VERY loud!). Reasonable gains of
around 10 HP can be reached by the use of the header on a stock car. The use
of a presilencer or straight pipe after the header does not effect HP.

We are not familiar with the Mindtrain product.

The racing beat header will replace the first cat or monolyth and as so, the header will be slightly longer than the manifold and the first cat, so it will not bolt to the remaing main cat. You will need as mentioned before a presilenser, or if needed Mazdatrix sells a high flow cat that bolts right on to the rb header making it a bolt-on system. I must tell you that the cat is very pricey.... I have that setup in my 82 and sounds and respond really nice...

 

just remember--rotary engines are louder than conventional piston engines... and rotary engies will burn MUCH hotter than a piston engine--they burn almost twice as hot as a 4-cyl...

i have a complete bolt on racing street port exhaust system from RB and i love it to death... it sounds great (nice low rumble, no rice cooker) and does gives quite a bit of extra power.
