free flowing cat

[Flashmn]

Heres a small mod regarding a catalytic converter...
Starting point, a brand new in the box magnaflow stainless cat with 2.5" in and outlet.


After some small modification..


...to be continued.

Fake cat?

[Flashmn]

no it was a real cat... without the innards now... but like i said to be continued, its not over yet. stay tuned

[Flashmn]

As continues.

So I make a pipe with some holes in it


Then I migged it inside the cat after filling it with glass-wool


Tadaa and I have a free flowing muffler that looks like a cat.

Are you putting in place of your cat or going to use it as a muffler? I'm confused on which your going for, a REALLY FREE FLOWING CAT, or unique looking muffler lol

If it's for the muffler I don't see the point

Putting it in place of the cat to use as a muffler. Therefor I'll have the cat underneath the car, but instead of it being a cat it will be a muffler and the guy who inspects the car wont fail it due to lack of a catalytic converter. (must install one if you add a turbocharger on post 1987 cars)

aha... very sneeky... so what happenes when they actually check the emissions? and doesn't the ae92 already have a cat? why not just modify the existing one?

[freakinbox]

ah, here in Canada ae92's all have cats, even if they are N/A. It's a fine here if you don't have one. mom's friend was telling me he put a hockey stick through the ones he had on his Transam lol

thats crafty. and i have never looked inside a cat before either.

Well the emissions dont change, they still are 3.5% CO and 600 PPM HC. And no our AE92's dont have cats, they only started getting cats with EFI in 90-91.

[Criard]

tricky! what kind of gains would you expect from that?

[Flashmn]

Not really gains, but I'm planning on more dampening with this. Not to mention if I'll run my car rich I'll kill the cat in no time.

[freakinbox]

yeah, and cats aren't anything special to look inside, like a honecomb type of thing...

Maybe I'll get my car E-Tested and do what you did, should be my car's last e-test unless they change the laws on 20 year old cars not needing them.

[TenZen]

they dont test cars for emissions around here. would help as some cars just blow out black smoke like there is no tomorrow
