All right i think i am getting confused....our cars do or dont have a header on them. coulda swore i read something like they dont come stock on them(could be cuz im tired that i am reading only sections)

Also what would someone recommend on a stock port motor with no mods....for an exhaust system....plz tell me whut parts i need to do so...i kinda want to go catless so i can take out the airpump....so plz list everything....

Thanks James

There is no head, but there is an exhaust manifold (header), which can be replaced with a better flowing unit.

As for exhaust system I recomend doing a search, opinions vary GREATLY.

i suggest racing beat. they're pricy though

Well if your an NA with stock port then a true dual system would give you the best mid range power.
Mid range is what your usually in the most so I would believe that's the best.

The N1's and Corksport will flow a lot because they are big diameter and would give a bit more top end but reduce bottom end by a bit.

The Single exhaust like Corksport and a bonez superflo downpipe would probably be the cheapest. I have this and spent around $600 for it all.
The true dual if bought completely costs over a grand from someone (I think Mazdatrix)
but can probably be made custom for less. Just buy Racing Beats uncolected racing header and then fab up the rest.

Now how hard is it to make straight pipe piping....my dad has a machine shop so i got all materials, welder, mills...etc. so should i buy a racing beat D/P and make my dual from there.???? or whut ....thanks digi....for the help

Quick question on this topic:
Was reading up on true dual exhaust and was wondering the difference between a "Y" pipe and true dual (looks not performance). The previous owner of my 87 N/A installed a dual muffler system, but im pretty sure he used a "Y" pipe. how can you tell the difference? Is there 2 seperate pipes from each muffler that go all the way to the front of the car? (for true dual)
Thanks

at the risk of sounding stupid, think of WHY it is called a y-pipe....

True duals are two SEPARATE pipes that each run from the engine to the mufflers...They are not connected to each other at all as far as flow goes. But a y-pipe has one pipe running from the manifold or headers, and then splits near the back of the car to go to 2 mufflers. It is basically "fake dual exhaust"

I get really pissed when people refer to the dual rear muuflers as "fake". Please stick your mouth over both tips and tell me which one is the fake...

zer0_to_6ixty

Went out and looked at my car in the dark, as i expected it's a Y pipe that joins at the front of the car.
heh "fake" dual exhuast

NZConvertible

"Fake" means it doesn't work. Did you do what I suggested to test how fake it was? Nah, didn't think so...

truespin88

it is dual exhaust if it has two exits that are not on the same side or of the same muffler (you can have duals exit beside each other, but of different mufflers, and you can have duals exit away from each other, but of the same muffler, but not together and of the same mufler... got it?)

HOWEVER... from a purist's standpoint... unless there are two pipes that go from the engine to the exhaust tip (seperate tips ) then it's not true duals... true duals implies seperate flow on each muffler/tip.

fake duals means that only one pipe flows exhaust, the other is for looks... certain dual exhaust systems (i.e. older grand ams) get more flow to one side due to the setup... but ah hell... this doesnt make any sense anyway...

skydivr73

EXACTLY---**** there NZ....you need to go get laid or something....just so you get a clue, EXHAUST refers to the pipes from engine to tail, NOT just the ****** mufflers. So before you decide to be a complete tool on here next time maybe you should sit back and wait for your laxative to kick in before posting! Why the **** is it called a "cat-back EXHAUST system" for example, if dual exhaust only refers to the tail pipes?? yeah, I thought so....go check out EVERY place there is to get exhaust for our cars, and tell me how many of them sell EXHAUST SYSTEMS that are more than just two mufflers.....ALL OF THEM.....or for that matter, tell me why the true dual is marketed as exactly that....

skydivr73

ahh, NO....FAKE means it isn't REAL, and when DUAL means TWO, but there is only ONE pipe that splits into two tails, that is not DUAL.

I never said that one side doesnt flow. No one else did either. So why be such a tool about something that no one ever said??

I like my True dual exhaust from Mazda Trix w/ Racing Beat mufflers... It made a "huge" difference at 40mph+ speeds! I have an aluminum flywheel that I put in before I got the exhaust system, it made the biggest difference in the low end, when i put the exhaust system on i think i lost a little bit of low end, due to less back pressure. But it was deffinately worth it!

The exhaust system along with HKS SMF intake filter and adapter came to = $1504.xx (shipped) It was spendy but worth every penny! and sounds awesome! The vid at the link does not do justice! It tunes out from bout 6,500-8k rpm and sounds unbelieveable!

I'm selling a RB header and possibly a RP cat back exhaust sytem off an 87 SE. The stock setup for these cars is terrible. Basically a big cast iron block and a pipe sticking off it. PM me if interested. True dual I think is supposed to be the best. At one point i heard it's a good idea to run a pipe between the two though to equalize pressure but I'm not sure if who ever said that had any idea what they were talking about.

NZConvertible

Just did, but thanks for the suggestion...
You sound a lot more upset than I ever did. At least I didn't need to resort to breaking forum rules by flaming. Take a chill pill.
You're ranting, not making much sense and missing point entirely.
Isn't real? So it's just a figment of my imagination? If you asked anybody what a "fake" exhaust was, they'd say one that wasn't hooked up to anything and doesn't flow. Thus a system that splits from one pipe to two isn't fake. The engineering reasons for doing this have been covered many times before. And most people here know that a "dual system" is one with two rear mufflers fitted like stock. That's why we use "true dual" to differential the NA-only two-pipe system.
More flames... You called it fake. Fake means no flow. Simple.

truespin88

wow... uh... i didn't mean to cause a flame war. you kids need to go get some sleep or something.

skydivr73

FAKE as in FAKE DUALS dumbass!! Not a fake exhaust, but fake DUALS....which means that the exhaust is NOT dual popes from the engine back....what you have is one pipe that splits into two mufflers....if I said it was FAKE, that would be one thing, but sonce I said fake DUALS that is another. Quit wasting my time with your stupid **** and take it word for word. You dont hafta change around what I said or leave out certain words to make yourself look smarter....cuz it really isnt working trust me.

Ask anyone what a FAKE DUAL setup is, and they will tell you that it is a single pipe that splits into two tails....go try it and tell me what you find!! Go call up a muffler shop and ask them the difference between FAKE DUALS and TRUE DUALS and then you tell us how smart you are Mr. Wizard....

truespin88

Wow, er, uh... such anger.

tannji

I think a defining factor here would be that he didnt ask about fake dual Mufflers, he asked about fake dual exhaust. A fake dual muffler might have no flow to one of the cans. I dont see how fake dual exhaust could be construed to mean anything other than a system with a Y-pipe. Other than to someone who lives under a bridge and stalks billy goats compulsively.

I don't want to get in the ring her but my two cents is this, dual exhaust is anything with 2 mufflers, true dual is anything with two independant pipes. Thats what I think *runs away*

eternalblinkerman

Perhaps siemese duals....still connected at birth...lol

NZConvertible

skydivr73, I'm not going to bother with this if you can't act your age. You sound like a stroppy 18yo kid.

skydivr73

See that NZ?? Maybe you should think about the fact that I am obviously not the only one to come to this conclusion....so if you think you have such reason to come off s o high and mighty about how it pisses you off when someone states the obvious, you shouldnt be surprised with the response you get. Of course you won't bother now....after all, you sound off so big until everyone who posts disagrees with you....

NZConvertible

No, I stick by what I post.

As I've said many times, there are solid engineering reasons for splitting a single pipe to two mufflers. It allows low-restriction exhaust systems to be kept quiet. That's why so many manufacturers do it. Notice how common it's become on new cars recently? Noise restrictions keep tightening, but consumers demand more power. So if both mufflers are there for a reason, how is the system fake?

Call it fake duals if you want. It's silly, because it implies a true dual system somehow better. Yeah, that'd work well on my turbo...

And you still sound like a kid.
