I've read quite a bit of conjecture as to whether post '06 4.8's can be fitted with headers or not. This is due to the three cats installed as opposed to pre '06 with a single cat.
The answer is yes it can be done, two high flow cats replace three and does it make a difference?
Oh hell yes!! This thing's a freaking rocket ship now!
And how's the fuel consumption ;)
Too scared to find out Clunk!
Do what I do mate...... Just drive and don't worry about it :D
Yest they can but 06 models only have 2 x O2 sensors where as after 06 (mine being 09) have 4 x O2 sensors.
At the moment there are very few headers / extractors that even have the ability to mount 2 O2 sensors.
Mines '07 OD and has 4 02 sensors as well. Do it, you won't believe the difference it makes. You're welcome to take mine for a spin if you like.
Smicko, cheers bud, am in perth so not sure if youre here but what make did you get as I cant find any that takes 4 o2 sensors
Never underestimate the power of the darkside, let the tap flow through you.
I added extractors and a 2.5 in system to my other 4x4, it was like I had another gear.
And knowing how Nissan choke these motors unleashing the beast must feel great.
You wont get fuel figures down till you wipe the smile off your face, enjoy the beast within
Nice to hear. I need to do this, but I'm not sure how many O2 sensors I have.
It's a 2011 model, but it's Gulf spec. I've heard that the Middle East Patrols still only have 2. Hope so.
OD they're Pacemakers, and yeah I'm in Perth too if you want to check out how mine was done.
That would be sweet, will pm you and try work something out
Holy mother of God this thing is NUTS, once I get over the fact that I can put three tonne sideways at will I'll have a crack at economy. I reckon I'm using half to two thirds of the throttle I was previously using at 100k's and it's a hell of a lot quicker in getting there. It's really, really hard to not speed. Not so good when you're on double or nothing.
could you pm me where you had it done, been looking into getting this done, i'm in perth as well
Give me a bell if you like PK, it's a tad complicated.

Id be keen to know where also. Im Looking at extractors and full system gor my 02 GU 4.8 :-)
I got the cat back done at Mettam's in Balcatta
was just a catback worthwhile?
Cheers
has made a difference as there were no extractors available at the time for the 09 model
Hey smicko, where did you go for fitting and roughly how much?
Mine was done as R&D by someone so as he could advise other fitters how to do it. Any fitter will be able to do it, they'll just need the parts from the bloke that fitted mine.
Basically it goes from extractors into twin hi flow cats then into the secondary which is 3" , the third cat is removed from the system, then main muffler and a resonator out the tail end.
Torque and throttle response has dramatically improved, especially in the bottom end, it revs far more freely and drives so much better. It is loud, not unbearable but it certainly barks. I just went through my first tank post fitting of 95ron e10 and it returned 4.8k's a litre, much the same as before. I refilled with 98ron premium so I'll see if that makes a difference.
I've been asked not to give out the guy that did mines details online as he is a supplier not a fitter (anymore) but my number is in this thread above and I'm happy to pass the info along verbally, same deal with price I'll pass that verbally so that you know whether you're getting stitched or not. As above, any of you are welcome to check mine out and have a spin to see if you want to invest the coin to do it.
Cheers
Mick
The extractors used are the same as for pre '07 it just needs a bit of custom pipe work to tie it all together.Quote:

i am from dubai as well and all models here is having two sensors only < by the way where you do your service in dubai
Yeah, I found out about the 2 sensors when my muffler broke a about a month ago. I got some headers and a drainpipe fitted down at a place in Um Ramool. It certainly made a difference. The car is much more responsive now. This is just an interim step for me. Early next year I will get a full exhaust done at Skyline exhausts (Fox) in Dubai.Quote:
