In the old days, cats were directional, like mufflers, and had arrows on them. 
Maybe these SHOULD be.......

I've installed a new pipe on a '91 with no EGR, and the cats will not 'light off'. 
That is, they will not heat up enough to start processing the exhaust, no matter how
I drive the car.  The only thing I haven't done is to put it on the track....the
rest of the suspension isn't yet up to the task of Thunderhill or somewhere else. 
I've driven it in 3rd gear at 80 mph on the freeway trying to get the exhaust hot. 
No luck.  

The exhaust exiting the tailpipes is noticeably cooler on our hands than Lowrider's,
or the black car's or any other car I've taken there.  They're acting like
mufflers....nothing more.

The smog guy (a test only station...no repairs done there) has said he has seen this
happen before.  He doesn't know what to do.  The car has since passed with the 10
degree timing plug pulled.  But it would be nice if it would actually operate
properly, since some day soon there will be roadside smog sensors that will zap this
car for NOx.

Any suggestions?
