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?

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.

    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
    • I'm interested,do you still have it?
