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

    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
