I manage a metallurgy laboratory.

If someone can arrange for sample of the substrate (a gram is plenty), I'll have an analysis back within 24 hours as to whether it contains any platinum group metals (Pt, Pd, etc) or indeed anything other than what's in a normal s/steel alloy.

Cheers

What's postage like from Australia to Bulgaria? :)

BOOSTD,

the 'metal cats' are good cats. we've tested those and they came up with good results on emissions, just like they clearly state.

the difference between the metal cat and this new catco cat is the body. the metal cat is quite small, i think its the same body size as the magic cat (4"), whereas the catco one is larger (5") and can pass through more exhaust gas than those. both have 200 cell pr sq inch catalysts, whereas magic cat has 300 cell per sq inch. this just means that the metal cat and catco cat have larger holes, thus being able to let through more exhuast gas than the magic cat.

either way though, the metal cat doesnt need cone reducers, as it already has them, like the catco cat, with 3" piping at the ends. the magic cat however needs all those extra bits (cone reducers, 3" piping) welded on, as its just a 4" pipe, this adds up, and because its not done by a machine, it would probably be quite rough in the end, depending on the skills of the person doing it for you at the exhaust shop...

keep a look out in the next issues in different magazines (e.g fast fours, HPI etc), you will notice hi-tech mufflers, liverpool exhaust and a few other well known exhaust shops advertise the new catco cats. i know hi-tech have been doing some dyno tests on the WRX with some very interesting dyno results.

HAHAHAHAHAHH this is funny!

How many people have bought cats that are just a fancy straight through pipe?

You got ripped off guys :P

Must... not... feed... the... troll.....

You have evidence its just a straight through pipe? Post it up. Or is this just going to be like your tirade against import agents?

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
