Metallic Catylitic Converters?

Looks to be pretty high flow by the picture showing through it. Any cons? Pros?

Discuss.

I have had a Metal 'Cat (same idea as the one in the link above) on my car for several years. No fowl smells, but we don't have emissions testing here, so I can't comment that. I got it mainly because my car has very low ground clearance (3" from the ground to the front subframe) and the cat is a nice small package.

[IsaacHayes]

Only visual inspection here to make sure you have a cat. No tailpipe test.

Is it worth the extra money? Looks like it might flow more and not clog or ever fail.

It says 50 state legal for OBD1 cars and 49 states for OBD2 cars, that would make me think it will pass emissions - even if it was sniffed

I'm using the exact same one on my car. The metallic ones are supposed to last better under higher exhaust temps.

[IsaacHayes]

Cool, but are they worth it you think over a standard magnaflow cat?

Ive got a Metal 'Cat as well.

Why does it look like it wont clog?? it appears that it could clog just as easy... Looks very similar to a regular cat intside.

I have on right now for sale it is 3" though 50 plus shipping if anyone wants it. The are basically like a resonator that gets rid of some COx. I have used them before and they do work really well for flow but they are not as good as a normal cat. So if you are close on emissions then back away.

[IsaacHayes]

Well it's metal instead of ceramic, so the chances of it busting up is less, and it appears the cells are bigger.

I did some reading and they do flow a tiny bit more, and are more resistant to heat (the ceramic ones use a cheap ceramic that isn't high temp like most ceramics) so they work well if you are boosted and running rich.

Younggun88, if it wasn't 3" I'd take it. I'm not boosted so I don't need that large. Thanks though.

[19Cutlass94]

yeah the cells are a little bigger. There a 200cell per square inch. I dont know what the stock ones are. They claim 534CFM...

But they are quite expensive. I bought mine for like $200. You can try ebay or something to that sort and you might find one alot cheaper.

[IsaacHayes]

Yeah like the magnaflow one in my first post. $114.18 shipped.

[Younggun88]

you could always use reducers prob cheaper still.

[IsaacHayes]

Not sure how that would affect exhaust velocity though by slowing it down with the large cavity causing turbulence. What brand is yours?

[Younggun88]

Not sure i can take pics if wanted just give me your email address. Also it has an o2 bung in it for a WB or 2nd sensor can always be sealed up with a bung.
