I was told my stao I need a high flowing cat. What should I get? Xforce 100cell metal cat? Catco ceramic high flow? Who has a metal cat and what did it cost. I would gut my cat and weld a pipe in there but I'm abit iffy about that. I'm in nsw and was quoted 320 for the metal xforce but I heard bad things.

Are these tested and tried brands? I've looked through alot on ebay and they all seem generic with a brand stamped on them. Venom stands out as it is tested and street legal which the others mention nothing of. I'm going to ditch the xforce because apparently they too are chinese untested, illegal stuff. 5" body sounds tasty too.

I have the venom sitting in the garage if you want to have look before buying. I can take it to work which is closer to your place if it helps.

It has much better materials, welding etc than my last one that is rattling itself to death. Ceramic biscuit fail on the old one.

He can do 3.5" flanges. He has bolt on kits suitable for most cars ready to go. Mine is already in post and I payed 12am this morning!

I asked him about the egt sensor port he said they don't come with them but they can be modded to suit. He didn't mention if he does it, nor did I ask. If I wanted it, I would just get a high tensile thick nut, same thread as the sensor, drill a hole in the end of the cat then weld it ontop. Wouldn't be hard. Then again, my old r33 did not even run the temp sensor.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
