I just came back from the dyno and my GTR did a nice 260 whp at 12 psi with GT-SS ( sarcasm :ph34r: ). My tuner said I NEED to change my cat, we found some piece of the cat on the ground it's really block.

What are my option !? I don't want some cravy 600$ sard or nismo cat. I want to keep the oem look. So, I was thinking about buying a high-flow cat and weld the heat shield on it so I can keep that oem-look.

What do you guys think?

Why do you want to weld the heat shield onto a hi flow cat? Its not like there illegal, people only weld the stock heatshield on when there using a stright pipe to make it look stock.

Hey Cobraa,

If you have a look on Ebay, there are a couple of cats, the main one manufactured by a workshop in western australia that are reasonably cheap $200 - $230 in 4 or 5".

They use 100cpi metal matrix if i remmember correctly and these should flow sufficiently for your GT-SS's and at that price if your really chasing the power you can probably afford to knock the internals out for use on the track :D

I'm after one too

AFter researching Just Jap have the most resonable stock.

Catco/Xforce $175 each bolt on.

450+CFM. $370 for the 700CFM.

I'm probably gonna get the xforce $175 one

*edit btw Catco ones COME with the heatshield.

*edit again, there was a dyno done somewhere, hiflow vs testpipe. No HP difference. Obviously crap cat vs highflow/test pipe would be obvious. So just stick with Hi flow for legality purposes.

There was a test done. Something stupidly low

lame! makes me want to remove mine again, but right now it's the only thing holding back the annoying drone at 2000rpm

X-Force 3" Stainless High Flow Cat

it flows up to 570 cfm...

anyone know what a stock cat would flow roughly?

I got one of these on my r32 gtr making 205awkw @ 6000rpm with just exhaust, pods and 14psi. Seems to do the job good for the price!

I would also like to know this!

My muffler shop told me about magnaflow cat.. but that 175$ catco seems right too. Don't know which one flow better.

Straight pipes all the way mate

I actually run a high flow catalytic converter business, which drastically increases the flow through the unit whilst retaining the standard shell :)

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
