alright guys I am going to be buying a Racing Beat exhaust soon, so which one do you think is better?

I have to do emissions so I will use my old cat to pass.

thanks

Get the collected system, that way you only have two swap out the header and presilencer for your stock exhaust manifold+cats when emissions rolls by. With the road race exhaust system you would need to swap out the ENTIRE exhaust system.

well were I live they don't do a visual inspection, so I wont have to remove the header to pass.

I gess my question is, is true daul going to be better performance wise?

jerd_hambone

oh my goodness, please hope and pray you don't get flamed like crazy haha

there are alot of people who would say the road race exhaust is better, and some say the collected is better

some people like the sound the road race system has, like me

but most people are going to say get the collected

no ones really had any proof of which is better, that i've seen anyways

lots of people post these big long scientific explanations of why the collected is better

but no ones really show any cold hard proof of which is better

i wish i could help you out some more.

i can find my old thread of a big 5 page long discussion of which is better

i'll send you the link if you wish :]

Well, get the whole exhaust system from the front all the way to back (if there is new catalyst converter included)

thats the best help i can give you

i hope it works for you

well thanks for the link I read threw it, but no one could prove which one is better, so...

Well, then I would suggest to do more research on it.

Patience is a virtue.

I recommend you to go to nearest Rotary Specialist shop to talk to them to see which one is better.

Beside Racing Beat, you can consider for Apexi or HKS.

One thing to consider is how much noise you're willing to put up with. Keeping the stock manifold will have slightly less power potential but will sound nicer and be a bit quieter. With headers you can get a pack of angry bees in the engine bay sound (so I've read). The stock cast iron manifold will not sound like that. You can still get a downpipe for the NA that bolts to the stock manifold and goes to the precilencer (stock manifold and downpipe replace header).

I like Apexi they do have better quality in their parts... I have their exhaust on my Stang and my buddy has the racingbeat on his... Not only do I have a deeper throatier sound it looks to be a straighter pipe system... just my $.02

what do you guys think of this particular one?? http://www.rx7store.net/product_p/rbfullexhaust.htm I'm thinkin bout buyin it for my T2....

iSP33D-for-J3SUS

Rotary Performance here in Texas recommends the collected system, as do I.

When it all comes down to it, it's personal preference. Just my .02!

SUPPOSEDLY... lol...

the Dual system is gonna make more power up to 7k rpm, with the sacrifice of "quietness" and power above that range...

the collected system is supposed to be good all around, and would probably better suit a S5 engine.

now, from personal experience...

collected - buzzy, good power all the way up, easier to deal with....

dual - sounds like a harley kinda at low rpms, sounds weird/baddish but you get used to it and it sounds ok.. however i dont like that it never "humms" it even at 7500 rpm still sounds seperated and dosnt sound right to me. as for power, the true dual system actually seems to have more low end grunt then mid range is about equal feeling then up high kinda dies compared to collected...

Oh, I forgot to mention, I am not going to do any porting on the engine. So what I've heard if your not porting the engine there is not going to be a big performance difference between a header and the stock exhaust manifold. Is this true?

Yes I will do some more research. But as far as Apexi and HKS gos, I like the look of the racing beat better, sooo yeah.

thanks

the.white.fc3s

well,

It's trading off or others.

You want the performance with durability OR you want the look?

Think about it...

Again, Patience is a virtue.

That's true, if you get the racing beat "downpipe" and presilencer you'll still notive a very large difference. Adding a header in your case just may add noise. The Road Race system is a very unique sound and isn't as loud as people say it is, but it IS a head-turner.

90FC

well, I thought that the Racing Beat exhaust could give me all of that.

Black91n/a

I can tell you from experiance that the racing beat system is a top quality piece. It is 100% stainless steel with stainless packing in the presilencer to prevent it from disintegrating with the heat, it has nice thick walled pipes for durability and it helps prevent that stupid buzzy 4 banger ricer sound, and beautiful welds on it. I would expect that it'll outlast my car, no question about it. I can't immagine how anything else could be of higher quality. It's also one of the quietest systems out there for the FC (still plenty lound).

JMY952

By any chance, does anyone have any soundclips of RACINGBEAT that they would like to share

the.white.fc3s

Dude,

Ok you say the looks.

After few years, it breaks down. Are you gonna spend more money on this whole system?

What I was saying that if you want to keep your FC3S longer, why don't you invest a little more on Performance and Durability instead of crappy durability with good looking?

That's why I am still searching for RE Amemiya parts because they are specialized on rotary. Sure, I would consider Apexi and HKS.

Look up the BMI, there is none of Racing Beat parts for FC3S. Most of them from Apexi (for ECU such as Power PC ) OR Re Amemiya (God of Rotary Tuner). Back in Japan, people will question, "What duh heck is Racing Beat? I never heard of them"

Again, Patience is a virtue. Why don't you do more research and at the same time save more money for better parts.

If you say that you don't have much money, I would say that sorry to hear that... this is the way that you pay the prize for keeping the legendary classic car. That's the way to keep your legendary classic car happy. Ask all the classic car collectors... they do spend a lot of time and money to keep their cars longer.

Just because something's from Japan doesn't make it better. Racing Beat has an excellent reputation here in North America, and Japanese tuners don't use their parts because it's an American company based out of Anaheim, California. I'd highly doubt that the RE Amemiya or Apexi is any higher quality, and it'll cost probably more than 2x as much as an RB system. Racing Beat is (well was, they branched out a bit) a rotory specialist, they've been tuning RX's for years, and have even set some land speed records (FC, 238mph in 1986 for example). Have you even ever seen a RB exhaust? I wouldn't think so, otherwise you wouldn't be bashing them so much. I have one (got it a couple years ago) and the quality is impecable, and the durability is impecable too, given a good cleaning it'd look practically new again.

I see no reason to get a RE Amemiya system unless you're one of those JDM nuts where everything has to be from Japan, or if you just have to have something that's rare over here, but you'll pay out your *** for that (rare due to cost I'm sure). With RE Amemiya, when you buy their stuff, you're funding their racing team, I'd rather fund my own racing efforts by buying something just as good for less money and spending the rest on going racing myself.

robtechfabrications

i agree black...with re you're just buying the name

EXCEPT

with **** they have that nobody else really makes, like that dead sexy rear diffuser. you better believe im buyin one of those instead of the rear bumper when i kit my 7

How could you not gain power with a header, the stock header is complete garbage. It's a giant iron box with two holes in, one hole out. That can't possibly be good for airflow.

The stock cat(s) would take the place of the downpipe and presilencer on collected RB system, the true dual system doesn't let you do this at all. So you would have to hook up your entire original exhaust when you go in for emissions rather than just that one section unless you bought their dual cat. The RB website says all of this btw but it seemed you didn't know that bit.

hey people, im new to the rotary scene, im coming from a honda background and im thinking about the Apex'i N1 or maybe GT dual exhaust for my 86 GXL. I know it's got a T2 hood on it, not my idea. First owners.

I know im probably gonna get flamed for mentioning the "H" word but im seriously into my new mazda and im looking for some real advice. I mean i've never even heard of RB or RE Amemiya so i just want to get an idea of wut's out there so i dont waste money, because god knows i did enough of that on my civic.
