Lukey extractors or pacemakers?

[vs v6]

Hey guys i have a vs v6 and have finally saved up money to buy some extractors
but dont know which ones i should buy? lukey or pacemakers?
some adivce would be nice, thanks!

[stuntmanmike]

100% Pacemakers. You won't be disappointed...

[Parraeels101]

Pacemakers for sure

[F l a k]

Yup, go Pacemakers.

[The1]

HM Headers if you can afford it, pacemakers are still very good!

[GTP 85]

The v6's aint much of a powerhouse so it doesnt really matter which one you use.

Ive had the short extractors very similar to lukey's and they worked fine, only went to pacies cause i got some for free... Back to back on the dyno and it made less poke on the pacemakers, slight improvement up top. I also felt the engine was a bit more responsive on the 'cheap' brand extractors

[somefool]

the pacies are more for 'top end' powahh.
for for a road car, pay attention to RUF 231.

unless of course you can get a set for cheap, like me
the do make a nice exhaust note

[nalchlan]

red back extractors with 2.5" pipes is the way to go.

[vsv6dude]

Extractors are always one the last upgrades read V6 supercharged power plan (Note I am not recommending to buy his products)

MACE also says extractors is one of the last upgrades.

What mods have you made todate ?

What do you want out of the your car ?
eg quick acceleration off the mark, top end power, make more exhaust noise ?

This can influence what mods and in what order.

Money perhaps could be better spent elsewhere.

hey mate its only got, 2.5inch cat back exhaust and 2 hole mod in the airbox...
what should i spend the money on instead of extractors?

V6 Engine Questions and Answers

I know this site is not popular for purchase of stuff but the Q&A seems credible.

According to FIT factory headers on VS V6 supercharged are capable of flowing 270kws so I would guess the the natural aspirated vehicle would flow pretty good as well.

CAI intake or 2 holes in airbox and CAT back good.

I have the following mods
1. CAI holden super 6 with a 3" dia hole cut out of airbox to right of snorkel behind headlight
2. 2.25" CAT back straight thru system
3. 12mm manifold insulator (clean the injectors at the same time),
4. 82 deg thermostat
5. run 95 premium unleaded (for reduced engine knock and promote part durability from fatigue)
6. ACDelco rapidfire plugs (Not really a mod I have not read a bad report about these)
7. Latest OEM Holden Leads (not really a mod, LPG experts claim these are best for the V6 unlike the early VS leads)
8. Lukey air filter (dry non oil based unlike K & N)
9. Mobil 1 5w50 (My vehicle has always had full synthetic, don't switch to a PAO oil on an older vehicle leaks may occur)

I have kept the mods mild so that the factory memcal is not overchallenged and can compensate within its design safety parameters.

Currently contemplating getting a memcal that is customised to the mods providing the safety parameters of the OEM make are not compromised. Durability is the key on my performance list.

I have steered away from roller rockers as I believe I may lose some low end torque as most of the gains are from 2000 revs onwards.

I use extra money for proper regular scheduled servicing eg engine oil, oil filter, fuel filter, transmission flush, coolant flush etc.

If you are after top end power, noisier exhaust note, more torque (diff etc) then you need to get advice from others.

If you told us what you wanted from your car we could give you suggestions. However, with the right tip, a cat back gives a nice note.

I had a very nice exhaust set up from pacemaker. It was ashame i got a VK instead of another VS as i would have kept it for this VS.
This was attached to my V6. The coin was well worth it.


So if you can tell us the answers to vsv6dude we can answer your last question.

Thanks for all that, really helped.
Im actually thinking of the 12mm manifold insulator and 82 deg thermostat

[seq4x4]

You will need a tune too.

[vs v6]

You will need a tune too.

yeah for sure
you selling them pacemakers?

[seq4x4]

No. That was the exhaust on my VS 2 years ago. If you want a tune done, message the user "The1". He did my tune for my improved intake. Cost you $80.

You do realise you can throw a stage 3 cam on and it will still be within "safety parameters" of the OEM, Throw a pod filter on with a custom built enclosure with CAI, and put a 3.9 LSD on, still inside the "safety parameters"

Just remember there's a difference between Headers and Scavenging Headers.

[Not_An_Abba_Fan]

Just remember there's a difference between Headers and Scavenging Headers.

Not really, they are called extractors because that is what they do, extract the exhaust gases from the combustion chamber. This is called scavenging.

When extractors were first developed, the original manifolds were called headers because they were attached to the head. Then extractors came along and eventually were called headers too. It's more of an American term. But essentially, extractors and headers are the same, just the type are different. Tuned length where all primary pipes are the same length and join at one collector, and interfence, where the primary pipes join into a set of secondary pipes, then into a collector. They all scavenge, the real difference is where your peak torque is achieved.

[The1]

I think i missed the point i was trying to make, which is that yes the stock headers might handle flow upto 270kw it doesn't mean that there's no performance gain then between stock headers and extractors.

[vsv6dude]

Id like to know what the "Safety Parameters" are.

Safety parameters in my view are what my mechanic sees as mods requiring a retune on the dyno or long term component such as engine, transmission durability will be affected.

eg changing to a larger MAF or MAFLESS will require a retune as the ECU will not be able to compensate within its input tables.

[vsv6dude]

I think I know what you are trying to say, the point I am getting to is if stock headers flow quite well and the only mod is a CAT back system new headers may not be a value for money mod unless the stocks headers failed and they had to be replaced anyway.

I have read too many times new performance headers and CATback sports system = loss of torque and increase use of fuel.

There was one dyno joint complimenting themselves that having installed headers and CAT back system a healthy 104kw had been achieved at the rear wheels for V6 auto.

If only the guy new that 104kw is the standard rear horsepower with stock headers and stock exhaust.

IMO unless you are after noise stock headers in the majority of cases are more than adequate for mild mods with out the loss of low end torque.

I am not convinced stock headers cause sufficient restriction in the system requiring them to be changed for mild mods.

[The1]

i have never been able to get as much timing out of stock headers as with extractors as obviously the waste isn't extracted as well so knock comes on earlier. Obviously there is better gains with upgrades done elsewhere of coarse.

As far as Safety Parameters a stock tune i wouldn't call safe if you really want maximum longevity. Take Automatic for eg there setup to be as smooth shifting as possible, to do this a fair bit of slip has to happen which wears components more. As far as fueling BLM's can compensate a little but not enough for most large mods, a retune should really be done.

Just for interests sake what the maximum power gain you have got using extractors compared to stock headers ?
