Hi-flow cat 3" $250 -300. I have no cat, which is better than gutting it, an empty cat still creates turbulance, which is bad. You can buy a cat remover, which comes with tags to add a cat exterior over a straight bit of pipe.

Is this legal?

T.

Any removal of a cat is ilegal!(These cat remover pipes are for competition use only)

Also it's $250-$300 + fitting cause they aren't bolt in items!!

Carsound is a good brand of high flow cats!!, and they are true high flow cats!(have fitted hundreds of the them, mostly to Holden's and Ford's though but have done a few Skyline's, Supra's , Soarer's and a few other imports!

And for all those who think that the term "high flow cat" is an oxy-moron.

Here is some tests done on a LS-1 chev(sorry couldn't find a Skyline one) with modifying the standard cats and comparing them to high flow ones on the flow bench.

Here is the link:

Also I personaly couldn't run my car without a catalytic converter as the power increase would only be approx 3%, and even less compared to a high flow catalytic converter, this also would make any car a rolling defect notice and make it even more destructive to the atmosphere!

I had a high-flow cat in mine, and since it's removal have had no issues and the car is producing more power. I had to remove it to run rotational idle and anti-lag, I don't recommend this approach to most people, just those after serious power. And yes there are legal and enviromental rammifications.

i just bought a 3 inch catco cat which should be hear next week.

cost me $170 brand new. i just got to get the flanges put on.

its a stainless steal one too. will let u know how it is. but i will not be able to tell the difference as it will be on the car from the very start once it gets started up.

Bit confused on the difference between gutting a cat and fitting a 3-inch hi flow cat.

What is the advantage / disadvantage of doing either ??

When you say gutting the cat, does that mean the standard cat or an aftermarket one ??

Reason i ask is that i have a 3-inch dump into a 2.5 inch cat and then 3 inch piping from the cat back.

Which one is going to work better for me - gutting the 2.5inch cat or fitting a 3inch high flow ??

i think by gutting he is refering to just having a straight through pipe with the cat casing on the outside to keep it looking leagal

i think u should go the 3" pipe, i always like doing something properly from the start unless its way out of reach. if u have to pay that little bit extra then do it otherwise u will pay for a 2.5, then want a 3" and so your paying more than u originally would of

Hey guys,

I know the guy who produces the parts for CATCO (Jappsport uses their cats for compliance and he comes by to sell them to us), so I can get any1 thats interested, a CATCO 3 INCH HI-FLOW CAT with the flanges for $160. You can come and pick it up from where I work in liverpool, sydney (Jappsport) or i can ship it to you interstate for a little extra.

I can also get 3 inch dump+front pipes (one piece, easy to bolt on) for r33 and r32 for $260.  

If you want a 3 inch stainless steel pipe, its $100 extra.  

I can also supply you with front+dump pipes for 180sx.

These I get from the same person that produces the cats for CATCO.

cheers

BATMBL: How about the above parts for an R34?

Can you get the CATCO cat and dump / font pipes? And are the prices similar?

I already have a 3.5 inch cat-back exhaust. I am assuming this stuff would complete my exhaust system?

Thanks!

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • 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 without 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.
