TUFXRT6 Silver Donating Members 687 Member For: 18y 7m 26d Gender: Male Location: Victoria Posted 22/08/07 07:07 AM Author Share Posted 22/08/07 07:07 AM I came across these guys that sell them for $440 http://www.justjap.com/parts_ncats.htm. The xforce one is just as good flowing apparently (metalic) and about $300 on ebay. www.catco.com.au has some comparisons. I think the benefit of these 2 cats is that they provide close to 0 restriction on a 3" pipe where the metal cat is about 10%. When it comes to performance sometimes it's worth paying a little extraHow come you have decided not to change your exhaust system???RegardsTUFXRT6 Link to comment Share on other sites More sharing options...

Then why not a bigger turbo? rebuilt gearbox? cams etc etc. Where does it all end, so I've drawn the line. I plan to fit a cat when the stock one fails, or let it "evaporate" as I wouldn't mind a little more from 4-6000rpm Link to comment Share on other sites More sharing options...

I would prefer to leave the CAT unchanged if I can get similar figures to you..OzzieMine's a Dec 03 BA mk I sequential, you can see the mods in my sig, add valve springs and you'd have an even higher top end number (it has a great low to mid range, as good as most 330 odd rwkw cars). Nizpro get 330rwkw+ with their stage 2 cobra kit which uses the stock cat so it's not unheard of. Obviously a gutted cat would perform better but it's illegal, depends how important an extra 20 - 30rwkw's is to the owner I guess, personally I'm happy with my power atm, maybe when I go to trade it in and realise how much it has depreciated I'll spend a bit more on it Link to comment Share on other sites More sharing options...
