Tuned length extractors or Normal?

[Lukezen27]

And yes I’ve Searched

OK Im going to get extractors tho I can't see where anyone is talking about Tuned length or Normal ones?

And would it make much diff to my D16Y VTec?

And where In Sydney should I got?

Chatswoood would be wicked :)

Thx LukeZen

Tuned is best - anyone can weld a set of pipes together... that's why a lot of Aussie ones are crap.

Tuned means that they are designed to scavenge waste gasses in the most efficient manner to facilitate flow. You pay for the research but it's worth it.

eg: Stock B16A manifold is better than an Aussie crap untuned header... in your case, you may see marginal return... but I'd be dubious.

[ENDLESS]

Manifold are designed to let the engine to breath better.... as you know B16 is a 4 Cylinder engine.. and the amount of gas coming out from the engine is almost 100% the same(as there are some tolerance, and all engines have different wear) so... when you have tunned length manifold the gas out of the engine can creat its own suction effect thus help the exhaust to pull out the exhaust gas.... However a good manifold requires a lot of testing, becaus e the length and the size of the pipes all have to be tested according the the air flow rate. The length of the primary pipes can also be varied depending on the cycle of each rev... it is all very complex calculations...

Anyway tunned length manifolds are definetly better, and a well designed (with calculation of air flow rate) will be the best choice.

I have a set of headers on my d16y, i think they do make a difference. The motor has a better air flow, it gives me a little more performance, it seems to rev out a bit harder. They work more effectively with an air filter fitted, and of course it chews a little more gas. I had mine fitted at Liverpool exhausts.

Cool,

thx for the info guys :)

there look nice but are they good

it won't fit on yr non vtec
the heads are different

DC sports make a header for the D series motors just in case your interested. A plc in sydney brings them in.

how much are we talking here?
and where abouts are they?

Talked to the guys @ best Mufflers and they said

2” Xforce header and Xforce Muffler but leave the middle piping to keep low end power?

He said he dose the exhaust for his mates VTec (races it) and 2” all the way was to big

He would make more $ form me going 2” so I figure he must know something

What do ya think?

The blokes at best mufflers weren't even able to supply me with the right extractors for my motor, in fact they think a B16A is actually called a D16A (no not the D16A8;))

ouch

thats not good :rolleyes:

How good are the tuned length 4-1 for sohc vtec headers tanghy sells?

No brand
mugen replicas

A lot more cash but maybe there worth it?

Thx Luke

[Cyrus]

when u get headers,..4-1 may not be the necessary best one to go
it flows better but you do lose low end for top end....4-2-1 is more expensive i think but they do give a overall better performance.

OK Im lost now :o

So 4-1 are not tuned length but 4-2-1 are err

?

just listen to the armchair mechanics, they know best :thumbsup:

jords car goes hard. nothing wrong with his setup!

a set of 4-1 extractors will give better top end power but often result in some low end loss. 4-2-1 will give a broader spread in the power band but wont give as much top end gain. so basically 4-2-1 is more suited for everyday driving. it sounds like the guys at best mufflers dont know squat. if your going with extractors you have to replace the rest of the pipe or it will just bottle neck and the extractors wont do shite. 2" is fine. no way is it too big - if those guys reckon thats too big for a car which is raced, i'd say they are racing in their driveway. some peeps go with 2.25" piping as it can give slightly better top end, though often with slight losses in bottom end power and torque. really have to decide based on how you like to drive.

Cool man

thx

Now all Ihave to do is find some cheap 4-2-1's

Most I've seen so far are 4-1 for a SOHC D16Y engine :rolleyes:

I sure there out here somewhere ehheh


thx LukeZen

nicely said sivic :)

This is one of the cheaper options for a D series which I went for

Nice one bro :)

Next dum question from me is

WHat the hell is a cat back?

Thx LukeZen the noob

Im thinking of getting the xforce headers for my EK D16Y4 i think...

where can i get them??
and dose anyone know the price of the whole setup??

thanks guys

Yup

I just got the whole lot do yesterday

 XForce Headers
 XForce S12 Muffler
 Hi Flow Cat
 Biggest resonator the my Civic could fit to keep the noise down
 2” piping

All for $1150 fitted

Tho I just didn’t have enough for all stainless piping

http://www.bestmufflers.com/

And yes I could feel the difference straight away heheh

that's pretty good value in your package...

how much extra is it for stainless piping?

is there even a difference? from stainless steal and the normal piping besides for looks?

Yeah stainless lasts longer man

Nope did not even ask how much more as I was already $150 bucks over my budget
