Speaking of cats, guilt got the best of me, I put my Stromung, Magnaflow cat equipped pipe back on. The straight sure sounded nice, but......
So, I'll save the straight pipefor the day I turn this car into an SCCA dominating vintage racer..

I thought I'd pass on my catalytic converter saga.
Starting in calendar year 2009, California's CARB law requires "Pre-OBD-II,
California Legal" catalytic converters, which of course, are different than
those for the rest of the planet. In order to prove compliance, a special EO
(Executive Order) number must be laser-burned onto the bottom surface of the cat
so that it's visible to an inspector. (Even if these cats were still available
from the dealer, I suppose that they wouldn't be compliant??)
A place in Van Nuys, Ca, Diversified Environmental Catalysts lists a set (Pass
Side AU81313 and Driver Side AU81314) that include the flanges, mounting
brackets and pipes. I ordered a set for about $425 each and took 'em to a
muffler shop. (ref http://catalog.deccats.com/fmi/iwp/cgi?-db=DECWEBCATALOG&-loadframes)
The DEC pipes were bent using the types of mandrels you'd see at Midas - that
is, causing non-uniform diameter at each bend. (I don't really know how serious
this really is.) But more importantly, the 2 1/8" diameter tubing did not match
my Stebro exhaust diameter. Apparently, metric tubing is slightly smaller. The
OEM cat pipes were still perfect, so I decided to have the shop cut out the old
converters & install new ones, rather than use the DEC assemblies.
The Magnaflow 36035 converters the shop used were identical to the ones on the
DEC provided assemblies. The new cats are cylindrical as opposed to the
"flatter, pancake-style" originals. By the time I was done, I was out $700 and
still I have to pay shipping to return the DEC ones. (I can buy a Starbuck's
coffee with my savings, if I can only find one.)
I assume that the Magnaflow 36035's are all fifty-state legal, but I am not sure
about this. That damn EO number is very expensive. The muffler shop charged me
$275 each for them, although one place listed 'em for about $165 each.
Of course, now I feel very pious as I drive in sunny San Diego surrounded by all
the cross-border traffic from Mexico. Just the plume from many of those cars
and trucks would probably screw up a test being conducted at a Smog Test Center
just by driving by....
