Anyone Using Metalcat Catalytic Converter

[TYPE-R617]

As the title says and also did u weld it straight on or got flange welded on it for bolt on purpose and what do u think of the cat?

[Limbo]

Cat's good, gives better flow, even more than my hi-flow cat, noticed it straight away. I got flanges on both side.

[sifoo]

limbo can u be a lil more specific .. also the price?

[Eclipsor]

I'm using one. Just welded in there. Not sure what I had in there before but it made a bit of a noticable difference. Not much though. Doubt it's really worth the price I paid for it nearly 2 years ago. I think I paid $320 or something.

[xtercii]

apart from metal cat does anyone have any other suggestions?

[ProECU]

carsound

[Malenic1981]

I have metal cat (not the one made in syd company but one from Perth) it's welded in and it made big difference over stock cat, I would recomand it to anyone, but car gets a bit louder

[phantom_civic]

My bro has one in his car, its welded on.
Agree with Malenic1981 the sound does get louder.

[xtercii]

where can you get carsound cat?

[Limbo]

The main diff from the metal cat and my hi-flow was that this one didn't buzz with that wooshing sound from the extractors. I could notice the car revved more freely also. Certainly suprised me with the incease as i wasn't expecting much diff from the hi-flow. Certainly worth the money if your gonna do the entire exhaust and changing the cat.

i got mine at performance exhaust, in nth parramatta, can't rem price but was around teh $380 mark i think installed
PM me if you want the number and you can give them a call

Eclipsor - i don't think that they were around for that cheap 2 yrs ago, they've only just come into market recently, and they have been pretty expensive ($500+) until lately

Maybe your confusing with hi-flow cat?

[silver_screen]

Magic cat for me ;) best flowing cat in the market atm

[Limbo]

are you sure magic cat isn't just a brand of metal cat?

This is where I got it

Mustn't have been $320. More like $350.

[silver_screen]

well it doesnt say metal cat anywhere on it... just says magic cat..
:/

[jayjaydo]

they are two completely different brands.

check out this site see what they have to say about magic cat.

Is there a point to such a high flowing cat on an NA motor?
Not only it probably doesn't flow that much exhaust, but unlike turbo NA needs some backpressure?


Either which way,
www.bosimporting.com.au
Metal inside mesh 2.5" cato cat for $240 delivered or ceramic mesh 2.5" for $160 delivered
I was/am looking at these but friend has an 06 STi cat he is giving to me for free but unsure how good those things flow?

[silver_screen]

Thats true.. u want some flow with n/a but u also wanna have enough back pressure... and about that metal cat dissin the magics.. anyone can say anything about another product... Put both on the flow bench and see whos flow the most... Magic cats flow the most but cost more. metal cats r awesome in everyway, but 2nd best isnt where they wanna be

What the Metal Cat site claimed is that they have Carb certification, while the Magic Cat and other higher flowing ones don't. To get Carb certification, you have to submit the cat in for testing that it still fixes harmful NOx and SOx components and passes exhaust gas that is below California EPA limits.

Note, in the USA, if you use a non-Carb certified cat, you probably get the same fine as running without a cat.

[xtercii]

how about in oz? do we get any fines or any negative effects for using a non-carb certified cat?

NSW EPA site says that you cannot disable pollution control equipment. I assume that you cannot compromise the pollution scrubbing performance of a cat. But it is rare that you have to have your exhaust gases tested for a pinkslip unless someone has dobbed you in to the EPA. In the US and Canada, their equivalent of a pinkslip includes a yearly exhaust emissions test.

[xtercii]

what if you get done at a blitz, you have to go to epa to clear ur defects and would that have any impacts on having a non-carb cat?

[spetz]

Maybe you can claim ignorance and get away with it?

Regardless though, if the car is engineered and was tested for emissions why would it be checked again?

Either which way, I think that newer engines are well below the emission level requirement so even if the cat isn't certified it'd probably still pass emission levels? Not sure though

Carb-approval doesn't mean NSW (or VIC/SA/WA/QLD/NT/TAS) EPA approval. I reckon what will happen is that they will test your vehicle's emission levels to see if it meets the limits set by our local EPA. So you can still use the Magic Cat, but it has to work properly to pass emissions.

What the Metal Cat site implies is that the Magic Cat has higher flow but they sacrifice pollution control performance for that flow and hence did not send their cat for Carb testing.

[Limbo]

just make sure the steel cat has an EPA certificate and yo should be fine.
In relation to back pressure, you will usually get enough back pressure from the piping.

Ignorance is not an excuse. :)

Newer engines are below emission levels because of their cats and also variable valve timing. But no matter what, they still make NOx because of the higher combustion temperatures brought on by higher compression, and the cat's purpose is to convert NOx into less harmful compounds. If you want to be kind to the environment, to the people around your car, to your pets (especially those that are in the vicinity of your car), then make sure your cat is performing its duty.

[spetz]

Ignorance is a bliss!!! :)

[Limbo]

no its not! Its an on the spot fine! i think its a $10k fine or some crazy amount can't rem exactly

[silver_screen]

its 10k fine on the spot. and if u dun pay up.. ur ****ed :)

even my extremely hipo rx7 has a cat... and when its finished its gonna have 3. i love my enviroment so im gonna look after it

Maybe u should stop being a wanker spetz

[spetz]

ummm I never said not to run a cat?
I just said that if someone put a cat on that didn't meet emissions standards maybe just claim ignorance

Maybe you should shove that really sik hipo RX7 in your ass if you care so much about the enviroment? It'll block your hole and your cars

[preludacris]

lol

so is the xforce cat illegal then ?

[spetz]

But when do emissions get checked?
I thought it was only when you get it engineered?
And I don't see how you can get in trouble when say your cat blows, you take it to an exhaust shop and they fit one on.
You went and did the right thing to put a cat on, why get penalized when you didn't know?

Metal cats also allow for the 'honeycomb matrix' to have larger holes as the metal can have thinner layers. A ceramic needs to be very think walled to survive the furnace, so the thin metal used in a metal cat allows more flow as more flow can be gained.

I just got a metal cat put on my car three days ago - I was quoted $380 for the 2.5" cat not including fitting it or having flanges welded onto either side.

I can't give a valid comparison about how it performs because I had my JDM headers installed at the same time. All I can say for sure is it pulls cleanly and sounds wicked when my car comes hit its sweet spot at 5800rpm (also have a spoon axle back). :D

And there is no way the EPA or RTA will let you plead ignorance if you are defected or in trouble for something. You may not have intended this spetz, but your post made me think you were talking about running no cats and pleading ignorance if you get caught. No way I'm taking a $10K gamble I won't get pulled up for a couple hp or to save some money on a decent cat.

[Dylanamus]

I may be interested in a Metal Cat, but I'm trying to calculate which size to go with. I have a full. 2.5" exhaust, but I'm thinking if it's not too much trouble to taper a connection from the 3" cat to the 2.5" piping it will be even less restrictive. It's a technique I've heard many fors and againsts about. If anyone wants to bust this myth, be my guest.

[DC5TYPER]

Ive got a cat called Max Cat I think. Looks alot like the Metal Cat and yeah does it flow like hell. You can see right through the cat and Mechanic said its barely street legal, Anymore unrestricted and it would be unroadworthy. Very load but more then twice the flow compared to stock exhaust. :thumbsup:

[civicCXI]

have a read of this article if u r wondering about it's legality
