you didn't mention which rex you have<<

It's an '87 13b NA...FI...

Remember, my goal is to get it as close to what it will be in the
aircraft...sort of a rolling test bed.....I'd like to get it to the point
where the only difference between it on the RX-7 and the plane will be the
exhaust system.  Necessarily longer and more complex for the car.  I'll be
following Bruce's video, and Tracy's book as much as possible.  I want to
get started in small steps, learning and modifying as I go along.  I'm in no
hurry...so, as I think of questions, I ask.

The plane I'll be eventually putting it on is a Long EZ.  Eventually, I hope
to put two of them on a Defiant.  Have to build that yet, though! <G>

They are a piece that replaces all three cats with straight pipe with a

presilencer<<

If I can believe the Haynes manual, I only have 2 cats...haven't been under
it yet to confirm.  But, I do want to eliminate as much of the exhaust
system as I can.  A bit more cheaply than $160, though...unless I can use it
on the plane.  But I doubt that.

You may be able to sell good used cats on partstrader.com<<

That's a good suggestion...a few dollars coming back from time to time will
help a bit...I'll see what they look like when I get them off...still a
couple months away...a friend (and former boss) of mine goes to Florida
every year in December for the winter.  As soon as he and his wife leave,
I'm going to take over his garage and barn.  Hope to be finished by April
when they return.

Thanks for the suggestions, Hans...this is what I'm looking for!
