Sorry guys, I have been reading every searched topic related to this but would like some more info from those that have Extractors, specifcaly the pacemakers, would like to hear from some 3.0L owners if possible (3.5's welcome to comment as well of course)

When I got my Lukey Cat back fitted I honestly noticed pretty much zero change in performance, just a change in note and volume. It sounds pretty nice but at times I wish it were a bit louder. When the engine is cold it almost sounds stock. Ive got the 2.5" piping. Anyway im in the process of saving for a set of Pacy's, ive read some reports that they can make the exhaust louder?

Pretty much im after info on the following:

1: For those with the 3.0's, how low do they hang? Heard alot of reports of scraping them.
2: Was the gain in performance actually noticable? I probably gained a couple of KW with my zorst but honestly didn't notice anything. I don't really want to spent $600 odd if I won't even notice it.
3: What did they do to the exhaust noise. Louder? Deeper tone? No difference at all?

I apreciate comments, but please refraim from 'use the search button' posts, cause trust me ive been reading everything i can find.

i have a 3.5 and did notice a little difference...nothing huge. it revs a little harder when pushed. i only have the stock sports exhaust. louder???? yes a little bit, but once again FA. A little more burble when backing off. keep in mind that mods work a little better on manuals

So would you say it was worth the money? Seing as its a performance mod, like I said, Id want to be able to 'feel' the difference. If a dyno chart showed a 90000 kw gain and 10,000nm of torque, it would mean nothing to me if I couldn't actually notice the difference when giving it the boot.

My mate has a Pintara with an engine swap + Turbo. According to a dyno it gets 140kw ATW, and my god can I feel the difference. Being a passenger in his car is scary, he can be behind another car in 2nd, quickly pull out and gun it, when the revs get near shift point the tyres will start the slip. I know with my car the tyres only ever spin if I dump the clutch at a set of lights and give maybe half a spin on the 1st > 2nd shift. I want the crazy ass rocket ship feeling that his pintara has.

My partner and i both have a 3.0L- Mine is manual, his is Auto- another 3l 3rd gen in shed which is manual.
In regards to scraping:
- Partners car has now been raised (preparing to be the baby mover- sitting on compressed vrx springs) has no issues with scraping.
- My car has compressed superlows so obviously it scrapes everywhere but when you learn the concept of going over speed humps etc on an angle, you dont encounter the problem very much.

Couldnt really note too much difference in feeling more powerful or anything. The dyno that was done from before an after extractors only showed 1kw difference but was done at 2 different dynos so some will argue that it could have more of an increase.
If it means much to you though- the stock 3l manual in the shed had 15kws less than my car had with a 2.5' cat back exhaust and pacemakers.

I noticed a bit more torque across all rpm and a bit more of a more violent surge as it comes into the power band above 3500RPM

I had the whole exhaust done with extractors (using previous straight through muffler) and the sound between stock + muffler and completely new system with same muffler and extractors is nothing. infact it could even be quieter. Extractors should make **** all difference to the sound.

I had my first scraping issue this weekend (3.5L). Although that was with 4 ppl in the car + 2 ppls luggage.

:/

By the sounds of it, extractors aren't too much bang for your buck.

Nonetheless I will sitll get a set of pacemakers in the hopes that a chip further down the road will benefit.

I have had my pacemakers for 2yrs now, couldn't be more happy with them. My car is lowered 3" so naturally, the pacemakers will get dented/scratched eventually. Luckily it was the tow truck company that dented my and they replaced the front half under insurance for me.

I also have a 2.5" RedBack cat back, looking into changing the CAT to 2.5", as I think the 3.0L came with a 2.25" cat, not much difference I know, but it's getting old and I think it might be getting some what blocked.

Torque wise, yes, I strongly believe you get more torque above 3500RPM, with you foot planted, the acceleration from 1000rpm to 2500rpm is probably the same as stock, some would argue that from 2500-3500rpm there's more of a rush, but I can promise you that you will certainly get a bigger acceleration above 3500rpm, it somewhat feels like a smallish turbo, and in some cars (in mine anyway), you will get a "tzzzzzzzzzzz" when your car changes from 1st to 2nd gear, it's just the resonance of the extractors.

I can certainly feel the few extra horses from the driver's seat in my car, so I am a fan of the pacemakers.

P.S Install the pacemakers yourself or with a friend who have the tools, they retail for like $400ish. So it shouldn't cost you $600 to get it working.

How many km have you done in your car, Lachlan56? It's always possible your cat converter has collapsed and so is now the most restrictive part of your exhaust.

Thanks for that Whitedevil, thats the sort of response I was after :P And yeah that turboish noise seems to be with a few people that have pacemakers/rpw extractors and is hopefully something i can look forward too :)

As for installing them myself, lol not a chance. I have about as much mechanical knowledge as my cat.

Hey mate, Ive got a 3.5L and it looks like my flex piece has died so Im looking at Pacemakers myself, Ive been quoted $800 fitted for pacemakers and $960 with two new exhaust tips, owch.. But that is including the rest of the exhaust..

This price was in Perth, where are you located?

I just got my zorst done a few weeks ago, chances are they would have mentioned it :P

Also wouldnt it be making some horrible noises?

And i was quoted roughly $650 from Carline in Emu Plains for extractors fitted

i agree with other posts stating the difference is felt after the 3500rpm range. definitely happy with it. but as i found out with the mods i have done thus far, i need to fix the fuel feed problem. you can do heaps of breathing mods like i have done, but you will need to add things like a fuel pressure reg, flowed throttle body, barrys lean out kit etc. to make em more wothwhile.

Im waiting for Barry to PM me back in regards to instalation of his fuel Kit, Im thinking of getting it done as a kind of preperation for extractors mod.

dam your getting ripped. it costed me 300 to get exaust and extractors fitted into my tj.... off topic anyone that wants a redback exaust system be prepared for alot of stuffing around. when they put mine in they had to cut out something like 6inces out of it and then with pacemakers in they had to put the flex pipe in from the old exaust

What did you get done on your exhaust system? Just replace piping to 2.5inch and rear muffler? If so, change the resonator or a straight through one. That will make it louder and is alot cheaper than extractors. From what i read, extractors dont make any or little difference. So better off spending that money somewhere else.

Shanigans that was including the cost of the extractors :P

Oh and el3ment im not seeking a noise increase, it would be nice but I don't plan on spending extra cash just for noise. The Extractors are to be purely for the performance gain.

...then you'll definately be pleased. I know I was. It rev's so hard from anything above 3000rpm, whereas the car felt pretty much the same throughout the entire range before I put them on. Quite a noticeable difference in power. Really wish I had access to a dyno to prove it though...

It's the extra torque that you're feeling. Torque governs how fast you accelerate, which you can feel. You can't feel power really, unless you're a robot.

Pacemakers/RPW Extractors are designed to flow better compared to the stock headers, thus you will certainly increase the potential of your vehicle, the only cases when extractors don't make any difference is when you don't change your cat back exhaust as the bottle neck is still there. Does that make sense?

Summarising: If you have a stock exhaust system, you won't gain much from extractors, if you have a Cat back done, you will benefit greatly from extractors.

Well for what its worth, my 3.5L Verada will be getting the pacemaker extractors fitted by Genie in Myaree - Perth, they Dyno the car before and after so I will post up results when its done.

Either this friday or in a few weeks when I get a day off work.

That would be good AlphA

And yeah ive got a cat back fitted so extractors should be good.

*sigh*
If i wasnt such a poor uni student I would love to get cat back exhaust and extractors installed. Would surely help me crack a 14 :cry:

I saw your first post and just jumped straight to hyper space with out reading any other threads... so sorry if its been covered !

Ok lets go !

I fitted to my 1998 3.0l TF auto sedan the following exhaust:

pacemaker extractors
hi flow "steel cat"
2.5" exhaust pipe front to rear
24" straight thru hot dog style center muffler
24" oval high flow straight thu S/S rear muffler

$1,440 front to rear, fitted, drive in drive out !

this has been the single biggest increase in HP i noticed as i had fitted the K&N pannell filter a while before and also the unichip way later than I fitted the exhaust !
With all three its increadable !

I would like to add that the unichip as it turns out (thanks to wrong advise) may not be the best for the 3.0lt and I suggest you reserch a bit on the greedy piggyback apparently is more versatile !

Also the front exhaust on the standard magnas where it comes down from the block and the Y piece where it goes 6 into 1 exhaust is so unbeleivably restricted may be the reason why you did not recieve the boost you thought you might have !!

Scrapping
(I have super low spings on the front and lows at the rear)
yes I would say they hang down adout 20mm more than the standard but it scraps on the extractors and the flange !

i hope thats some useful info from some one who has done it !

i wish :bowrofl: nope, all up it cost $1000, that was for a complete cat back 2 1/2 redback exaust system and pacemaker extractors. shop around for installation prices. acording to most of the exaust shops i went to, they reconed it should take around 3 hours to fit. to do all of my system it took around 4 hours(took abit longer cos he hadn't put extractors on a 3.5l before and he didn't want to snap a bolt) but that incuded the exaust installation as well. i got quoted at one place $300 just for the extractors alone!!!! you may find that alot of places will look at you dumb too when you say that your putting extractors on a magna as well(i think most of us are used to that by now though) because most of them haven't put them on a v6 magna before. all i can say is find another member in your area that has done it before and see where they got theres done.
