Figure since the RB package is about $400 and the true dual header with twin presilencers is about $700 I would spend the extra cash. How much horsepower do you think the RB would put down compared to the Trix 35 RWHP?

i would get the RB stuff. I've got it and it's awesome. The true duals help with the overall powerband, but the header/presilencer probably produces more peak hp. Anyway, the slight midrange advantage of the trix duals is not worth $300. I'd say go with RB, the improvement for me was 40 bhp (butt horsepower).

Are you sure the RB provides that much horsepower? youre talking the streetable header and the presilencer combo right? im wondering what my car will be like with that and intake since I gutted my entire interior and under hood **** I didnt need.

the DUALS are WORTH IT if you don't have them don't post an oppinion on them. Sorry but unless you own a set and have driven the car with them you don't know a damned thing about them.

somone should do a 1/4 mile test with RB header/presilencer and with the true duals (I say 1/4, not dyno, because what the car actually runs is what matters, not the numbers). I would not be surprised to see the RB win.
1987RX7guy, have you ever driven a car with RB headers, etc?

Mazdaspeed sure has his opinion on them...I believe it went along the lines of...there worthless, waste of money, pieces of ****...or something similar to that. He had them too...

yeah i would opt for the header/pipe combo.. if you've allready got a good set of mufflers than you should be fine. I am going to match my hot Borla's to the rb header / pipe kit, when and if i ever get around to it.
think i'll see a diff in Power over the stock ex. manifold?

I did not mean to upset you so I apologize for it.
(I say 1/4, not dyno, because what the car actually runs is what matters, not the numbers)
That is a statement that is putting numbers against other numbers. 1/4 mile to HP
Now other things can affect the 1/4 mile suck as differing weights different(separate) mods and driver skill so I would have to have the same car on the same day and perform exactly the same on both runs to achive a perfect comparison of both systems. Also it matters what cat-back one chooses to run after the pre--silencer different cat-backs flow differently.
I still and probably will always stand by the Mazdatric TRUE DUALS
Oh and by the way the DUALs use RB components: road race header twin RB pre-silencers and two RB mufflers or HKs mufflers for about 200 dollars more.

You'd have to use the same car at the same temp to get a good comparison. If you did several runs you could get a pretty good comparison. Different cars have different compression, etc, so that doesn't really work.
I know the duals use rb components, but they don't have the collection effect, and it is pretty big. I actually get a kick at 6k or so when the scavenging effect is most efficient.

If you guys want a 1/4 mile comparison, then you got it!!
RarestRX has the header and true dual setup with mufflers and intake and he runs a 15.7@89
I have the racing beat header and presilencer with dual N1's and intake with the racing sleeves and I ran a 15.7@88
I don't remember his 60ft or anything like that, but if you search for his last drag racing post and my last drag racing post maybe you can analyze both of our numbers.
He has a GTUs, I have a GTU with GTUs driveline (trans and rearend). It doesn't get any closer than this. So check those out and analyze them

yeah, but do you both have the exact same engine? No, so the camparison doesn't really work. It has to be the SAME car.
All that does is show that it is close, and we all knew that was true.

If you have the time, and ability to make your own exaust I would. Idealy, you would want dual 2" exaust, with no collection. This comes from Rob@Pineapple. Here in the NW, his engines own alot of racing records. You look at the pro7 series, or the IT class, and all of his guys run dual 2" exaust.
Also, I've owned a full RB exaust, then swapped into a dual exaust. The dual is quicker for shure. CJ

a standard racing beat header to mufflers system vs. the true duals...in terms of how much power each system will produce on the same car is really about the same. the difference is where in the rev range that power is available...i would think that the standard RB system makes it's power higher in the range while the true duals makes a fatter mid-range band. either system is top notch in quality for sure but don't look to start smoking other NA's at the track bc of one system over another. an RB header car vs. a stock manifold car w/ a catback is a night and day difference. I still can't imagine how loud an NA must be with either true duals or a full header back RB system...I have the stock manifold with a custom 2.5 inch downpipe from the manifold back to an Apexi dual N1 system (flanged, no cats) and I couldn't go any louder.

Wel sorry about the low quality of the sound but here http://www.sonicrat.org/~fuckrice/sound/duals.wav
that is my car with a tape recorder on the rear bumper and a bit of reving in neutral. if you want to hear loud then go to my OPEN HEADERS thread and take a listen.

. Torque is increased greatly from 2000 RPM on up, with the power peaking at 7000 RPM
that is a quote from Mazdatrix
The true duals provide good power to the S4 redline and the power for S5's is probably the same or a bit better after 7k. The DUALS provide both good power areas in the mid range they have great torque and up high they keep going like the bunny

I have had 4 setups in the past 2 years.
1) Stock manifold through straight pipes to bombs. – LOUD - a little power gain.
2) Header to straight pipes to bombs. – WAY too LOUD! – nice power gain.
3) Header to single 3” silencer, Y to bombs. – nice tone – nice power gain.
4) Header to dual silencers to bombs. Nice stereo tone – nice power gain.
The bottom line:
Headers make almost all the power difference.
The duals give a torquey growl under load at mid band. Not a big difference in power, but they sound cool.
Click on the link in my sig to hear idle tone with a throttle blip.

I say this: the DUALs are GREAT and I personaly did not mine paying for them( why: they are bolt on, good quality, sound great, make awesome power) if you don't want to spend the cash then don't but the DUALS will rule until some other vendor cares enough about an N/a to make a tuned single race exhaust.(not likely to happen) It comes down to what you are willing to do either the duals or a "tuned" single

It will be a LOT easier to tune the exhaust with a single then a true dual exhaust that is not collected in any way. They seem to be a good very streetable exhaust, but they are heavy.
By the way 1987 Tuned single, not hard to do. Just do the math and find out where you want your exhaust optimized and have the tubes colected at that length.
And whenever we talk exhaust I want ppl to read these articles http://personal.riverusers.com/~yawpower/techindx.html

Im kinda lost when people say "tuned" single exhaust. I planned on just buying the streetable header with either the presilencer or just a pipe (electronic 6 ports) and then get that single bolt on that has the muffler on the driver side, but am now confused with "tuned"
