extractors

[St Jimmy]

Where is the best place to buy some extractors seen some on gebay the other week but they dident seem that cheep. Can i buy them cheeper from a exuast place. any places in newcastle

[cjdeane10]

ebay item: $180

I thought that seemed fairly cheap (includes shipping to most places in Ausr), however you will still need to fork out for the rest of the exhaust system which will add to the cost...


not sure what a full 2" system and extractors (inc fitting) is... Anyone?

i havent got extractors for the zuk yet, but i welded up one for my old ford escort from some 2" stainless steel pipe (straight pipe), bought a high peformance muffler and extractors sperately, and all up cost little more than 200 bucks (from memory). Was considering doing something similar with the zuk.

[Highway-Star]

I think it was $450 for my extractors and complete 2" exhaust with muffler, fitted. (about $220 of which was the extractors themselves)

Didn't need a new cat, but if i did, they are quite expensive ($200 or something). If your current one is stuffed, exhaust place won't do the exhaust without replacing it.

I found the extractors for $85 at a wreckers, and got a 2" exhaust made up and fitted today for $280, total of $365 and she now can climb hills, and reach 100km/h!

You little ripper!

Hi

Ive heard that extractors add alot to a 1.3l suzuki motor

Any one out there that can give an unbiase opinion or actual facts on the extractors vs standard manifold

Thanks

I think that if you could turn the extra "go fast" noise off i would be surprised if you could pick it.

Maybe 10%.... which is the very edge of what is seat of the pants detectable, and much of this might be due to a fresh cat and free flowing exhaust system.

some claim to feel an improved top end, but the risk there is that the motor starts to lean out at the higher revs with more gas flow.

Unless you do it on a dyno, you can't trust the seat of the pants due to the increased noise. It just sounds faster

Mistrust your own pants Steve,
Mine don't lie.

It is better. There is a noticeable increase in power, as attested to by the big hill near my place. Since i got the ute, I have been able to tell you which reflector pole i will reach before having to drop back to fourth.

It went over the top today in 5th. Sailed through it in fact.

Yes it sounds better at idle, but i can't hear the difference in 5th gear because of the noises from my gearbox anyway , so i didn't have that to bias my opinion.

It was worth it. Absolutely i would recommend it.

i agree with gwagonsteve did nothing for mine but the sound. cheers ron

OK Rabbit in an attempt to be unbiased:

Facts:
The standard manifold cracks eventually, to it may need replacing anyway.
Fuel efficiency on my car increased from about 10 km/L to about 10.5 km/L. This is in 2WD road use, without a load in summer (damn variables).

Opinion:
It increases power, not wonderfully, but is defininitly an improvement. I dare say it helps mid range torque more than anything, as my acceleration from about 2500 through to around 4000 rpm is where the most noticable difference was. The noise is a personal opinion, personally I think it sounds better cold, and slowly accelerating at low revs; otherwise it sounds rather average.

I have a two year old set of extractors that I have just taken off my old motor. They won't go on the M13A so if anyone wants them, $100.

[MightyMouse]

Sometimes fitting extractors/headers changes the shape of the
power/torque curve in that it can make a surprising difference in the feel
of the car afterwards - without making a lot more power.

For off road use the actual tuned lengths of the pipes will be way too
short ( unless you are revving it hard ) - but the pipes will probably flow
better than a stock manifold - so one again the feel will probably be
different.

Just shifting the torque curve can make an improvement - but often the
noise and the fact that $$ have been spent convinces people there must
be more power......

zero difference vote from me carby 1600 just noisy

[Gwagensteve]

There's a few other variables here that are impossible to test unless you did a before and after on a dyno, but small "problems" with timing/fuelling might be assisted by extractors (or more importantly, the better flowing exhaust system that comes with them) which is where some of the "under the curve" gains that MightyMouse is referring to might occur.

I still vote that there will not be any miraculous gains. It might well feel a "little bit better" but for 90% of people I would say in a blind test (and without a change in exhaust noise) you wouldn't pick it.

PS cars with extractors on them don't have to sound any way in particular either. In a mate of Greg's postman's car, we ran a G13BB with mandrel bent extractors into a 2" system with a high flow cat, one 14" hot dog, a triple flow muffler and a 12" hot dog.

It is soooooooo quiet, you can barely hear it at idle and you only get even a hint of note on big long rips at full throttle to high revs.

At idle, the injectors ticking are louder than the exhaust.

It's really nice to spot a car when you can talk to the driver whilst he is driving.

Steve.

here here.

gregs postmans cleaners car is the insparation for my exhaust.
it is nice to beable to have a conversation with the drive without having to raise your voice.

I noticed with extractors and exhaust system (2 inch) on mine that acceleration was a little better and it tends to hold speeds a bit better up hills. It's only a little gain in power but any extra horses helps. Now looking back at it the $450 spent could have gone to a 1.6

My 96 coily has a set of extractors fitted and apart from having a little more grunt on the highway and sounding like a trailbike, there's not much difference. I know from recent experience because while mine has been off the road I've been driving a WWII fibreglass willys jeep replica built from a stock 95 sierra chassis, running gear and donk. The jeep replica is a little bouncier than the coily but the performance on and off road is very similar.
