Mid_Nite_R33 Posted April 8, 2006 Share Posted April 8, 2006 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 ! Link to comment https://www.sau.com.au/forums/topic/112849-which-high-flow-cat-would-you-recommend/ Share on other sites More sharing options...
GTRsean Posted April 8, 2006 Share Posted April 8, 2006 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.

VHR32 Posted April 9, 2006 Share Posted April 9, 2006 (edited) http://www.surefloexhaust.com.au 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. http://www.metalcat.com.au/ Or try 'Magic cat' Edited April 9, 2006 by VHR32 Link to comment https://www.sau.com.au/forums/topic/112849-which-high-flow-cat-would-you-recommend/#findComment-2081840 Share on other sites More sharing options...
saliya Posted April 9, 2006 Share Posted April 9, 2006 (edited) 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.

Lunatic Dancer Posted April 9, 2006 Share Posted April 9, 2006 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...

AlexCim Posted April 9, 2006 Share Posted April 9, 2006 there is a good brand going around, called PUNCHED Na just kidding, dont punch your cat.

WazR32GTSt Posted April 9, 2006 Share Posted April 9, 2006 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 Link to comment https://www.sau.com.au/forums/topic/112849-which-high-flow-cat-would-you-recommend/#findComment-2082669 Share on other sites More sharing options...

Also how much for it? On the JustJap website they only have a high flow 3 inch which I assume is ceramic inside...

aquariuz6 Posted April 10, 2006 Share Posted April 10, 2006 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.

redline2003 Posted April 10, 2006 Share Posted April 10, 2006 Thats sounds pretty good. Best price I could find was $740 landed and taxes paid. While some other shop quoted me $1100, plain rip off. Think ill go for an APEXi cat. Link to comment https://www.sau.com.au/forums/topic/112849-which-high-flow-cat-would-you-recommend/#findComment-2085206 Share on other sites More sharing options...

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.
