Which of the two are better? would you ratehr buy a sdj (stainless steel) or racing beat header?

TopGunM2k

Racing Beat specializes on rotary vehicles, therefore their exhaust components are made to withstand the extreme heat of a rotary engine.

SDJ makes 20+ more hp. It is a true race header. The pictures on their web site don't do it justice. It is a piece of art. All the front runners at the SCCA Runoffs run the SDJ. For street the RB will work fine.

The question should be which one would I rather pay for. The answer a used RB one. Although I would love one of those SDJ ones.

SDJ would be my dream header.

But at that price..... it's hard to justify. I've seen one in person and it's just a work of art. I'm planning on buying one and using it for a while to get the stainless blue discoloring... take it off, and mount it on a wall. Then sell it as art. With the profits, I'll buy another one.

It's a long shot, but someone in LA is crazy enough to buy it and I'll get a free header out of the fiasco. If you want to use this idea, go ahead and let me know if it works...

Does SDJ do the whole complete rear end too or do they just do headers? if they only do headers what do the guys in the scca use for the rear end ? RB?

Rotofire

Do you have a link to SDJ? I'm nowhere new to rotarys and I haven't heard of it before!

I've got a RB unit, and while the design isn't optimal, it's a good upgrade for street and light autocross use. It is heavier than hell though, and the stainless steel units are half the weight.

so anyone know what people like to use with their SDJ header? 3" straight pipes?

MosesX605

Depends on if you like your ears to bleed or not.

What is the car being used for? If it's street use only, you're going to need at least two presilencers and a baffled muffler to make the car quiet enough not to attract attention. I have two presilencers and a straight through muffler and I have to *****-foot it around town so as not to get the fuzz on my tail.

Piping size, I'd stick with 2.5 as an absolute max on a stock port. I'm actually running 2.25 right now, and it is a good mix of power gains plus some retention of low end. My old RX-7 had 3 inch straight pipe after the manifold and it didn't have any low end grunt at all.

so good combo would be sdj headers (or RB if money does get on the low side), 2.5" pipes with 2 silencers. I'm also planning to do a big street port or even bridge port later on. I want my car to be a daily driver but also to kick *** on track and for hauling pony's or what ever comes up

personally I love the way the rb looks, I havent seen the SDJ in person but it look pretty cool...

how much is a SDJ header?

680RWHP12A

i paid $650 and it was worth every penny!!!

iTrader: (40)

does this thing really make 20+ more hp then the RB header? If so why the constant miss information about Racing Beat being the best if there is such a better product out there.

680RWHP12A

racing beat is the best for the price

its not the best product...

the sdj header is hand built out of stainless material and is bad ***!!!

don't look at it as misinformation. as Robert points out:
yes, this part is key.

although i'd never heard of this company before, i have read several sources that show the design shortcomings of the RB headers. however, no other company comes close to producing a better unit for the same price. you have so many people bitching about RB parts being expensive - how many do you think would shell out $650 for something better?

Hyper4mance2k

iTrader: (40)

me if i had known about it a few years ago

rxseven07

650 doesnt seem that bad... because of the rarity you see! in almost everybodys sigs you see "racing beat header" how many people honestly have " sdj header... im getting one... does a racing beat pre silencer bolt up to it u think?

BMS2004

with that giant flange at the end it won't bolt right up. I'd like to see a dyno with same car and swapping headers before I believe this great thing. Sure its lighter, sure its pretty. The point i'm getting at is the two camps are preaching two totally different theories. RB says its best to have the two exhuats pulses connect as far back as possible. SDJ on the other hand obviously crosses them over alot earlier. which is better? I'm not sure. Maybe SDJ's product uses the high velocity of the hotter earlier exhaust to scavenge better. Or maybe all those extra early bends do something.

Rotor13B

I agree with BMS2004. We need dyno proven results from some third party that is not going to fudge the findings in there favor.

rxseven07

**** let them give me the headers and ill gladly do it!!!

iTrader: (3)

yeah, i wouldn't be one bickering about the price either, as long as my research got me to believe their claim, the cost wouldn't be a factor. i was merely saying that i strongly feel that most people would balk - even some that talk a good game. that's all ...

yeah, i know ... a test would be interesting. a system based on the SDJ header vs. an RB Streetport system.

why don't we just get forum members that have both come together and test dyno them out .... anyone out there willing to do that ??
