and your fuel economy goes out of the window.......plus if u get caught without a cat its a massive finage.....i prefer a high flow cat.....its a lot better then not having a cat.....the power difference from having a high flow cat to no cat is like 2 kw difference.....so not worth the fine i say

stock gtr cat = win

im getting a pipe through my cat now anyway, took my car to rob at rampage this arvo, my cat is welded on so he has to cut it to fit the new front/dump pipe anyway.so i said to just knock it out and put 3 inch pipe through it, that way, it still looks like i have one.

i know they are smelly with no cats,i did it to my old 5 litre VS stato that had full zorst, boy that thing loved to pop flamage..

fuel consumption doesnt bother me, i rarely drive it.

im just scared that it may sound i little tinny?

it will sound a little louder, and a little barkier.

i run a cat, cos i dont want to hurt the environment! :blink::P:D:D

who claims your econo goes out the windows :blink: to my knowledge this is lies

after personally driving same car with cat and without mine hasn't changed from a cat

take the cat off, DO NOT CHOP the cat sensor.

Get a Chisel & a Drill and a good set of manly hands. Whack the absoloute F*** out of the inside of the cat untill all the Ceramic/Metallic substance is gone (depending on cat)

Offers absoloutly no flow restrictions, when the cops shine a light under your car they can see you have a cat & you will be fine. If you get defected and they do an emmisions test, which they most definately will, then your forked, so dont be an idiot and have a whinge when you dont get through regency with a guttered cat.

    • You Gregged a whole racetrack!?
    • 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...
