well headers and true dual are for n/as while downpipes are for turbos

powrdby13B

no, i think you best explain what the **** you're talkin about... because i still haven't found any helpful info in any of your posts...
and i'm still tryin to figure out what the **** that true dual thing is all about...
and good job for quoting the whole post, you're smarter than we all expected...
edit;; just read kouki's post... lol, yeah.. thats what i get for posting at midnight... i didn't specify na or turbo... guess i should have...

Uh.. so tell me "Mr. Know-it-all".. have you ever seen a true dual setup for the turbo II? and look at the damn thread topic.. True-duals.. Obviously it's for an NA. Close this thread moderators..

powrdby13B

actually yes. It involved a twin turbo. It was a track car, and he had run straight pipes back, with one turbo connected to each rotor, so eat **** bitch

powrdby13B

yeah, thats what i ****** thought.
i'm takin my *** to bed... pm me if you wanna start some more ****

You're are ******* dumb as ****. . enough said

wow, you guys... just wow.

anyways. someone asked what true duals are. its one exhaust pipe for each combustion chamber, thus the name true duals. two pipes going from the engine block all the way to the muffler cans. one pipe hooks up to combustion chamber 1, other pipe = combustion chamber 2. get it now?

if a four cylinder had this system, it would have four exhaust pipes, 4 mufflers, etc. if a V8 had this setup, well thats a lot of exhaust pipe and uneeded weight, which is why you rarely see this type of setup on non rotary cars.

V8's... since they usually have two headers... have a sort of true dual... except for them it's not really all that special... Last night when i posted my first post on this thread, i wasn't really thinking obviously and forgot to mention that those gains are only for turbo cars. For NA, divide those numbers roughly by two... or maybe 5/3... I wasn't actually trying to start a flame war... but when someone totally comes out and says i'm wrong... especially when i know what i'm talkin about... it's not so great... And you'll notice that I did say that i meant turbos on the first page of posts... and he still said i was wrong. Thats how it became a flame war. Sorry guys...

The 16.5 to 15.2 was a very special circumstance, and thats where clogged cats came from. That is true, and the guys only mods were exhaust and intake... And it was a NA car too. And he did get a 50 HP gain over a clogged *** system.

Its like a couple of 6th grade girls fighting over what color pen to use. God dang guys, this form is supos to be fun. A place to share good times and knowlage, Not to fight like a bunch of prissy beotches. Were all on the same side. If someone says "i have a 300rwhp NA" insted of flaming them, and saying how its not true, shut the hell up and listen to how they did it. Things are possible, Everything is possible with money(which some people here do have). Go scream in a pillow, because no one here cares about your negleted childhood(unless you ask for help... but then do it in the right thread). Now excuse me, im going to a honda forum, where they dont act like a bunch of special ed queers fighting over a speck of dust.

Stop posting and grow up a bit... Pansies

Back on topic. Dont get the duals unless your fighting over a fraction of a second on the 1/4 mile. Expect a healthy power gain from the headers. They says ~15hp gain, that means a MInimum of 15hp. So they can guarentee that. with a good exhaust, the headers will most likely put out more than that. Unless you want to pay big money for the true duals to show off, no reason to get em.

best wishes,

oh yeah, the 90na had 160hp. He wants to know how much it will add ontop of his engines performance and potential. You dont get a 50hp gain even if you had clogged cats. if your car should have 150hp, and you have 100. that 50hp 'gain' isnt a gain, its filling in your power deficit. Who gives a crap if you do a ton of stuff to your engine, and have stock power- light gains. If thats the case, your car sucks, best mod, buy new car.

The only reason i've seen people get true duals is the sound. Sounds very nice...
Problem, of course, if you ever decide to go turbo thow :-D

I'm almost afraid to join this party... but maybe some of you are still not on the same page.

the keyword I noticed in that post is streetable
the "race only" (not emissions-legal) Racing Beat system allows a lot more power to be gained than their best emissions-legal setup does. Is that the big difference between your two stories? just asking.

nah one is talking about turbo and one n/as

This thread was fucked up so bad.

If we're talking about a header here, that's n/a not effing turbo.

If we're talking about a turbo here that 50 hp number might seem more reasonable because of the boost increase.

N/A's wont see a huge increase in full exhaust, like stated 5-10 or maybe more if you're lucky.

True duals are very expensive and there is no hard proven data that they give you more power over a collected header. I have yet to see anyone dyno both systems on the same car back to back, maybe someday, but until then it's just all talk which is better. My opinion is the streetable header is plenty good.

Yes it will get louder.

Flames will be easier because there is no cat, but other things effect them too.

There are times when true duals are better and there are times when a collected system is better. Neither system is better under every situation. A true dual system will make the best power for stock to streetported engines. Once you get over a streetported engine such as bridge and peripheral porting, you absolutely have to go with a collected system or you will be losing alot of power. I know that many people say that true duals always gives you the best power and they are full of crap and have obviously never played with ported engines and exhausts. It depends on the porting.

As some general information, the farther back you collect a rotary exhaust, the harder it is to quiet it down. A dual system for, all intents and purposes, is collected at infinity which is pretty far. The farther back you back you collect them, the lower the tone gets to. Don't confuse this with a low bass note type of sound where it just drones. That is determined by muffler. What I am referring to is the fact that a collected short primary exhaust may sound like a sport bike where a rear collected or uncollected exhaust may sound more like a Harley or a lawnmower. That is the tone difference. Muffler design does play a large role in the sound you get though.

Well i am running 2.5 with a presilencer and no cats and it backfires pretty loud. i never checked for flames though. I am going to just get a rb collected header and call it a day. Thanks for the info and flame war.
