these models all had 3
inline catalytic converters, BTW, which provided quite a bit of back
pressure reducing power.

This brings up a question I've been pondering.  I'm getting close to
putting
up the RX-7 for the winter, and do want to do some major mods on the
engine
this time.  Trying to get it as close to the configuration it'll be in
when
I get ready to mount it on the Long-EZ.  One of the things is to remove
the
cat converters.

Can anyone see anything else I may have to remove or modify if I do
this?
The emissions computer gonna complain if they're not there?  How about
pulling the oxygen sensor?

I installed the Mazdatrix headers on my 88 RX7 which removes the first cat
converter but does have a mounting boss for the O2 sensor.  This is the
quickest & easiest HP boost you can get on an RX7.  The increase is plainly
felt in the seat of your pants!
