Location: An island off southern Tasmania.		I have decided that these are not worth getting.

Have had so many problems with bad fit, rubbing on the sump under hard acceleration, flanges not mating correctly, and they sound like crap.

My recommendation...do not buy.

The latest thing to piss me off is i had the car towed home last night...sounded like a big end had come loose.

Nope...bloody RPW extractors have a cheap chinese flexible coupling that disintegrates internally rattling around with such violence that it trips the knock sensor and ECU goes into limp mode.

They are coming off ASAP...enough is enough.

You would have sworn it was engine failure.

Location: An island off southern Tasmania.		These extractors just keep going from bad to worse.

Found another problem on the firewall side...

these stupid 380 extractors from RPW just keep getting worse and worse...another crack found...


It's got shitty welds all over it this extractor kit.

Only 18 months old and falling apart.

If it was on the radiator side i would shrug my shoulders, but it's the firewall side, which really pisses me off.

Do not buy these bloody extractors, whoever fabricates them has NFI on how to do a continuos seam weld.

It's got harline cracks appearing all over the place.

700 bucks totally wasted in my opinion.

Man, those welds dont even look like they touch the pipes.

Funny thing is they are blue like pacemaker extractors which are supposed to be pretty good.

Got warranty, use it, show them pictures of the welds, cracks etc.

No $600 wont get you stainless, i sell mild steel Genies (rebranded as Redback) and they are close to that price, i can assure you they are not making me rich so the price he paid sounds very fair.

You are right mate, you get what you pay for, and the price wasnt a lot in terms of what one might spend.

But at the time its all that was and still is available for the 380.

I'm just pissed at how much work it will be to pull them off and put the stockies back in...and how long it took to find the limp home fault that was coming up randomly the last week.

Anyone with these extractors that gets intermittent performance issues should inspect the welds.

Early symptom was the rattle sound of what seemed like aloose heat shield when cold and at a particular rpm as well.

I reckon it was stuff all improvement, just a lot more money, more noise and more CEL's.

We got the bloody rear bank extractors out this afternoon.

Save yourself a lot of time..remove the drivers side driveshaft, else it will be impossible to get one of the bolts off.

Unplug the oxygen sensors on the firewall side just under the throttle body...lots of things in the way of course then simply push a flat blade in the plug clip...hard and pull on each plus (two man job)

I also removed the flange for the main exhaust pipe and moved it out of the way.

Remove the steering knuckle and lower wishbone clamp with 17mm sockets
and the axle bolt (32mm socket),
unbolt the TWO retaining bolts that hold the drivers side intermediate mount on (ball breaker task, needs universal, and three socket extensions and 14mm socket) both bolts are horizontally fitted, one is located by feel only...good luck

then it's a piece of cake, surprisingly easy actually.

Here's what it looks like at the point of failure...i can see daylight through the cracks of number #3 and number #2 was about to break through as well.

I am seriously pissed off with this extractor kit.

Location: An island off southern Tasmania.		Went to Exhaust Brothers in geelong and showed them the damaged RPW headers.

20 minutes and $30 later i'm driving away with some meaty reinforced extractors.

Then broke my balls for two hours getting the bloody things back in.

I love having a hoist at home....


It fired up sounding surprisingly quieter, maybe she's had a small crack for a long time?

oh well...time to go for a fang....

Have your mixtures checked on a dyno, without trying to sound like a smart arse, to have so many fail near the welds points to overheating from running lean.

One other question that may answer my first comment, is it on LPG? If so ill take back my first comment......Normal.

yeah it's LPG...can't you tell by the white pipe? i ran it on petrol to eliminate as many sub systems as possible when looking for the fault....so that explains the black bits...lol


Dyno shows AFR average about 12-13

Here is what she sounds like at half throttle.....


wasn't me driving, just a timid kid.
