Overkill on a standard car.

tell me someone who has left their car standard once they start one thing it always ends up being another,buy for the future and you save buying it twice .

overkill today perfect tomorrow.

I was thinking the cat might be a bit restrictive so gonna try a decat pipe next time it goes on the dyno to see

It still doesnt feel to bad I just want to eliminate that as a suspect, Tune might just be a little out so will see next time it goes on the dyno

The full X-Force exhaust system is great, I love the sound it puts out, nice RB sound without being overly loud

Guilty...............

If the car is tuned right..

My Xforce cat got kinda shrivelled up near the back and blocked SOLID to the point where the turbo blew a chunk of gasket out due to backpressure :P

this *may* have been due to running an ECU with no 02 sensor though.

That'll do it every time...

+1, got mine installed couple of month back, car seemed to pull a bit harder & boost seem to come on faster & its a lot quieter than my old exhaust (stock pipes with a cannon wielded on), no longer have the annoy drone at idle & doesn't sound like a lawn mower when I'm just driving alone at 60km/h at 2krpm.

Didn't knew that they weren't EPA approved though... good thing I still have my old exhaust somewhere...

i put on a 3" hi flow xforce cat over 1 year ago and i noticed a more free flowing exhaust with the odd back fire here and there on cold nights

the odd backfire would point towards airflow meter, or on a cold night the air is alot thicker (more oxygen in it) could be a bit lean, reasons are many for back fire, no offence but your giving miss infomation.

bakes got a metalcat put in his... didnt make a lick of difference to the power but gave a tad more torque and a bit more feeling under foot.. doesnt throw flames like it used to though.. and for the record.. bakes is a girl.. arent you bakes :woot:

Just Jap have told me they run a ceramic Catco in one of their 300awkw GTRs..

Just don't get Metal Cat confused with other companies "metalcats", Metal Cat is a Australia company that makes cats with metal castrates, The X-Force cat (copy of Metal Cat's cat) with the metal castrate isn't EPA approved (none of their cats are, its just X-Force trying to cash in on the metalcat name).

are metal cats street legal? Do they still make your exhust smell the same as when you have a normal cat in the car?

buy a catco metal cat ....please :)

Dont supposed anyone has tried the x-force exhaust manifolds? Im thinking about getting a low mount one. one of my mates rang them up (the place he works for is a dealer for x-force) and he told me the guy from x-force said they had early problems with the manifolds warping but they have fixed that in the latest version of them.

Just wanted to know if anyone had seen/used one?

Is it worth getting an xforce 'zaust or spending a bit more on a stainless HKS system? Sound = same?

I was thinking of a HKS silent hi-power from the turbo back w/ 3" dump & hi flow cat etc

    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
    • It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!      
    • Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
