Needs to be fabricated to....

yes, they keep a few in stock but for large orders they need to fabricate.

this is actually an old thread from last year, we've just used this one instead of making a new one. as a lot of the older information is still quite relevant.

with the addition of 4 door love we have 7 people, another 3 more would be good and we can go ahead.

Got my extractors at work today ... nice and orange lol

Just a quick heads up to people ...

I asked for a 2.5" oulet and they sent me a set of extractors with a 2" outlet ...

dunno why or what I can do about it ? I thought they only came in 2.25 or 2.5 inch not 2 inch ... I measured up with vernier calipers and it came out to exactly 2 inch ...

currently have a 2.5" exhaust system ... might have to get the exhaust shop to cut off the rear collector and weld on a 2.5" collector ...

will have to see what the exhaust shop say if they can cut the collector off and make up a 2.5" outlet or not

Ahh wells ... shit happens I guess ..

I am quite impatient at times and hate waiting for stuff ... when I want something I must have it like yesterday ...

Gonna fit the extractors myself and get the exhaust shop to then cut the collector off and make up a 2.5" collector back to the standard Cat converter then to my 2.5" exhaust ...

Hopefully I notice an improvement in low to mid range performance from what others have said it is noticeable so I will wait and see ...

My mate at the exhaust shop will more than likely want to put a flex joint in where the collector normally is to help with flex of the engine so that the exhaust doesn't crack so I will see what he recommends as he has done a couple performance exhausts for me in the past and has always put a flex joint in this position...

... Hope your group buy goes well :D

P.S - The extractors are nice and Orange :P

Quick heads up for people ...

These extractors are not just a quick bolt on job ... where they weld the pipes onto the header plate the welds are too large to put the spacers on so that you can bolt them on properly ... you will either have to die grind the welds down so you can fit the shims or modify the spacers somehow ... I gave my spacers a grind but it isn't good enuf to clear the welds so I will have to pull the extractors off and die grind some of there welds away so that I can tension them up properly ...

But I did notice a bloody huge difference in engine responsiveness and more power through the mid to high end range ... gets up to speed alot smoother and pickup is much better ...

You guys will notice the difference in power that's for sure ...

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
