hey guys,

Im looking for a 3inch high flow cat...

Got quoted $300 for a Magnaflow high flow cat, its body is quite long, is this brand any good?

Would I be better off with something like Cato large body cat or X force high flow ?

What would you recommend?

Cheers !

I put one of them high flow metal cats in my GTR (barrel shaped stainless steel one) it's the bomb. As much power as running without one....I paid $420 for mine last year. It had 3 inch end flanges on it.

Scroll down the LHS and click on 'catalytic converters' and have a read. They sound good to me. Most of these high flow style cats are around $450 though.

Or try 'Magic cat'

FWIW my mate that runs an exhaust shop reckons that the metalcat cats outflow the other high-performance cats he

has fitted (catco) He won't fit the magic cats, I'm not sure whether this is because he thinks they're crap or because they're

plain illegal.

www.metalcat.com.au reckons that the xforce and magic cats are illegal, because they don't have a 'CA stamp' (info

on the homepage). Would anyone that has an xforce or magic cat look on it to find a CA stamp?

I'm going to fit the biggest damn metalcat I can find to my new exhaust, won't really be able to post 'before' and 'after'

dyno results though.

Regards,

Saliya

I've just installed one of the xforce metal cats...3"

the actual cat bit is slightly larger, maybe 4" but the ends are 3"

driving wise I can definitely feel less restriction, boost comes on

earlier and quicker, less throttle at cruise, bit more responsive..

All in all I would say that its definitely worth it. Unfortunately I don't

have any experience with straight pipe replacement so can't comment

on that but I went from 3" catco high flow (large volume) to this and

can def. feel the difference..

Only problem is xforce ones don't come with anything stating its legal etc

like the metalcat type.. no stamps no nothing on the actual cat...

I'm getting the pfc tuned sometime this week and can post results if anyone

is interested... this is on sr20det with cams etc btw...

my xforce one has a sticker on the bottom saying it has been checked and certified, but there's no stamp on the biscuit material

you can't legally sell a catalytic converter if its not a catalytic converter.. companies would be up for millions in false advertising and civil lawsuits

Where did you get an X force 3 inch metal cat? Also how much for it?

On the JustJap website they only have a high flow 3 inch which I assume is ceramic inside...

what do you mean as in ceramic inside?

if your cat was ceramic inside does that mean the material of the honeycomb thing inside is ceramic not metal? what colour would that be?

i thought cats are all similar but high flows are 3mmx3mm spacing?

if you dont want restriction just hollow the cat.

Yea from what I've been hearing its the honeycomb inside of the cat thats either ceramic or metal, but im not sure what colours they are if you look at them.

      GTR R34 Limp Mode

      By GTSBoy · Posted

      Has equal chance of cleaning an AFM and f**king an AFM. I think you can work out what happened. When the Hitachi ECU sees the AFM die and goes into the associated limp mode, then it will start and run just fine, because it ignores the AFM and just runs on idle maps that will do what it needs to get it going. But there is no proper load signal, so that's about all it can do. My suggestion? If you don't want to go full aftermaket ECU, then get some R35 GTR AFM cards and some housings to put them in, in the stock location, and Nistune the ECU. Better to do a good upgrade than just replace shitty 40 year old tech with the same 40 year old tech.

      GTR R34 Limp Mode

      By steven7270 · Posted

      So my car was recently having trouble starting on initial crank, I would need to feather the gas for it to start up but besides that it would start and run fine. So I clicked the idle air control valve (with throttle body cleaner) and cleaned the MAF sensors (with MAF cleaner). The start up issue was fixed and now the car turns over without the assist of the throttle, but the car is in limp mode and wont rev past 2.5k RPM. From what I understand the IACV would not put the car in limp mode, so I am to believe it is the MAF sensors, but it was running fine before and now I cant get it out of limp mode. I cleaned the MAF made sure the o rings were seated properly. Made sure the cables were plugged in properly, the cables also both read the same voltage. Does anybody know why this is or what could be causing this or how to get it out of limp mode?

      Thanks. Yeah I realised that there's no way I'd be able to cover the holes with the filler, it would just fall through. Thanks again @GTSBoy!

      That was the reason I asked. If you were going to be fully bodge spec, then that type of filler is the extreme bodge way to fill a large gap. But seeing as you're going to use glass sheet, I would only use that fibre reinforced filler if there are places that need a "bit more" after you've finished laying in the sheet. Which, ideally, you wouldn't. You might use a blob of it underneath the sheet, if you need to provide some support from under to keep the level of your sheet repair up as high as it needs to be, to minimise the amount of filler you need on top. Even though you're going bodge spec here, using glass instead of metal, the same rules apply wrt not having half inch deep filler on the top of the repair. Thick filler always ends up shitting the bed earlier than thin filler.
