Ok i am looking to switch out my exaust manifold for some headers. This search has lead me twords an interest in a true dual setup but i have a few questions before i go this far.

1) is it louder than the stock pipes with the same mufflers?
2) would flames be more or less likely?
3) would true dual show a significant power increase over single+dual to justify the cost?

Also if i decide to go with a header to replace the manifold and keep the stock single+dual has anyone ever heard of the company PaceSetter?

Thanks for any advice or experience you can send my way, i did a search but couldnt find any answers.

Theres been a ton of stuff talked about on Pacesetter on this forum, keyword "pacesetter"...Also true duals and their potential have ALSO been talked about several times. key word "true duals".

from what I remember true duals do not show that much of a significant gain to justify what it costs, could be wrong, def. isnt worth the price of admission for me though.

If you really want a power boost you're gonn wanna fab a header...
then get a 2in/2out presilencer from like Holley or somebody and run like 3" piping back to it... then run 3" piping from that to some hi flow mufflers like N1's or something... and that will give you many many more HP's... like 50-75...
Or, optionally just get a full racing beat header back... thats worth a dyno tested 50...

toorbo?

what?

Uhh, 50-75 HP gain my ***.. Try more like 5-15 HP, if your motor is ported then maybe more..

Also this topic has been covered so many damn times. It's even been covered within the last 2-3 days, come on people.

you'd better tell that to all the rb owners out there. THey will be pissed.
Especially me... i had a na with intake/zost that ran a 14

powrdby13B

btw, thats 50 horses over a clogged to hell cat... thats basically coming up from the worst case scenario... lets say... 30 over a good stock exhaust. And haven't you ever heard that RB full exhaust (this is for a turbo) gives you a DYNO TESTED... maybe you missed that... 50 HP gain?
You can make a better header if you have access to the right equipment... but it will be a lot louder...

I have RB products, and have friends who own RB products. Even on the RB website, they state that their collected (streetable) system gains an average of 5-7 HP. So your telling me that a true dual system will gain a net of 50-75 HP? Your on crack.

Wow, you had an N/A that runs a 14.. woopty friggin doo.

Does that have anything to do with this topic?

powrdby13B

umm yes... i think that has something to do with the fact that i said the only mods are EXHAUST and INTAKE...
want me to upload the dyno chart?
Oh yeah, i forgot... some guy said the rb system took him from a 16.5 to a 15.2... and he had the slip to prove it... explain that to me then...

Mx6-Rx7 Addict

Your dyno sheet proves absolutely nothing, for all i could know, you could be spraying..

Also i really don't care...

Moderators, please close this darn thread..

then why'd you make a big deal out of it? oooooh yeah... y00's a h00... LoL... sorry dude, i didn't mean to start ****... but if you have a clogged to hell cat and shitty *** mufflers then you will get a 50 hp boost... and there's some way to figure that out using some form of math... feel free to look it up...

Obviously, your 500 posts have nothing to show for. The topic was never even started about a "used-to-have-cloggd-cats, now-has-50-more-hp-" Car...

Do some research my friend..

powrdby13B

oh okay, so i tried to be nice... let that be noted..
okay so its been proven time and time again that with a full exhaust from racing beat you can take a car from mid 16's to low 15's. Try getting that into your head.. that does have to do with the thread... still with me? Good. Or wait, are you gonna argue with that, because i'm startin to think that if you saw a car run a 12 you might think it ran a 15 because no ****** way could anything short of a 20b run anythig lower than a 14...
Okay, so now, still with me... thats good... you can make a better header, but not much better, and it requires everythign (hangers included) to be custom. Holley parts are the best, somewhat undisputed (well, except you probably know where to find better parts... but their the best for everyone but you), so you could get slightly higher numbers using them. Right? okay, so therefore using LOGIC... which is something i suggest you familiarize yourself with... we can conclude that the gain would be >50 HP. Right?

well if stock S5s dyno at about 130 hp a 50 hp gain would be 180+ rwhp?
I've only seen one do that and it has some more mods than just full exhaust and intake.

Mx6-Rx7 Addict

That made my head hurt.. And to summarize because i'm tired of typing back to you, You said a 50-75 HP gain, not "1.4 seconds quicker in the 1/4". There are so many things that have to do with a quicker e.t. (clutch, tires, driver, suspension, air temps, track conditions).. So you still have absolutely nothing to prove that a full exhaust will put 50-75 more horsepower to the ground, and you still make no sense. Go away..

powrdby13B

ah, but see this isn't just any S5... its the one that only makes 100 rwhp because the cats are clogged to hell and such... its the one that kinda sputters whenever it runs...
plus, open headers make a big gain in HP... plus remember i'm talkin about turbos so lets say more like 30-ish...
And that 50 might have been for a ported motor too... not so sure off the top of my head...

powrdby13B

okay, completely stock except for exhaust 1.3 NOT 1.4 second gain. Sorry, i thought you might be able to think for yourself... let me help you... would you like a bib? Now, okay, your 1/4 mile time improves when the only improvement to the car is performance mods, right? that does happen, right? okay, so you got that goin for ya, and the decrease in 1/4 time is roughly inversely log/exp related to the HP gain. That didn't go over your head, did it? So, if we do some math, (just arithmetic, don't get scared) we see that it takes ROUGHLY 50 RWHP to take a car from 16.5 to 15.2. Still there? good.

Ok.. So are you talking about non turbo or turbo?? You keep changing your mind..

Yes, on a Turbo FC, you will net a gain of much more.. Stated by Racing beat:

"The Turbo II High Performance Exhaust system incorporates a 3.15-inch (80mm) down pipe from the turbo outlet that mates to a presilencer section. From the head of the Y-pipe two 2.375-inch (60mm) pipes extend to the ceramic wool-packed 304-stainless steel rear main mufflers. The bolt-on exhaust system increases horsepower approximately 32% - a 59 HP increase on a 1987 Turbo II RX-7!"

He is talking about an N/A, not a TII.

but then again why talk about a car that has clogged cats?
Sure if you are talking about a specific case but you seem to say that a full exhaust will gain 50hp.
Id say its more like 30rwhp.

powrdby13B

i seem to remember saying something about those numbers being for a turbo... i spose i didn't indicate that MY PERSONAL car that i was talking about was turboed, i guess i figured you'd be able to put 2 & 2 together and figure that out...
but nice research, you get a cookie for being smart. In fact, i dont think i realized how smart you are that you figured out that i was talking about turbos, like HOLY **** DUDE, youre fuckign smart dude... your fuckign leet man you pwned my *** i feel like a n00b... i dont think i'm gonna be able to sleep tonight because you pwned me sooo bad dude holy **** i fuckign cant believe it... omfg... wow it hurts just to think about it...
So, ******* READ THE POST before you start talkin **** next time, eh?

Mx6-Rx7 Addict

I did read the thread
Haha, so when do they put true dual on a turbo car?
Go back to highschool, GED's aren't the way..

powrdby13B

dumbass, remember that, you coulda said, oh, yeah, turbos maybe, but he's talkin about NA then and not made us both look stupid... but thanks anyway...
For a NA i'd say 30 sounds good, koukifc3s...
TO SUM IT UP... closer to 50 with good cats, closer to 75 with clogged cats. On a turbo. Take those numbers times 3/5 for a NA. Agreed? Jesus ******* christ i wanna go to bed

the thing is we're talking about an n/a here

sure TIIs get much better gains since they are allowed to run more boost

powrdby13B

dude, wtf are you talkin about?
