It'll be just fine, especially if it's an OE type and not some small hokey
aftermarket el cheapo cat.

I use various cats here and there making Subaru exhaust systems and so
forth.

I wouldn't expect the slightest problem.

And.....BTW - I believe that a hollowed out cat does not flow as properly
as a cat with good catalyst material in it.
    If you know what principle an expansion chamber on a two-stroke engine
works by, you might wonder about the dynamics of pressure waves in a
hollowed  out cat, and how it might not be right.  The entire system, from
air intake onward, to the tail pipe, was engineered to have a cat in there.


I always run a good cat.

Btw, the chances of back yard 'creativity' - taking short cuts, leaving
things off, and thus having less than what you optimally hoped for - are
pretty good.      . If you don't REALLY know what you are doing - stay very
close to stock and that's how you get the best results.

Hi all.



Going to harvest a few things from an '85 Vanagon. I assume it has a 1.9.



If the cat looks ok, could i use it on a Jetta 2.0 engine?



I imagine that since the displacement is larger, then no. But if yes,

then I can save a few bucks.....



....... especially since I'd be installing a cat voluntarily.



(AFAIK, up here an '81 air cooled doesn't require it. Pretty sure no

one would notice if I didn't have it. Just trying to run cleaner)



Thanks much for any input.



Neil.
