[DML] Re: "Fake" converter available

["content22207" <brobertson@xxxxxxxxxxxx>]

I'd relate de-emissioning to rural vs urban rather than any specific
geopolitical entity...

De-emissioned cars driven recreationally are far less hazardous to the
environment than fully emissioned ones driven daily in commuter
traffic. Length of American journeys is also a factor --
environmentally sensitive Europeans existed into the late 80's without
emissions because their cars were simply driven shorter distances
(European automobile use now approximates America circa 1970's, while
American journeys have nearly doubled since then). Note that increased
American automobile use is largely due to suburban sprawl -- again an
urban issue. Rural driving patterns have remained fairly constant over
the decades. Traffic congestion is another urban rather than rural
phenomenon.

That said, as an owner of a catalytic converter-less DeLorean, with
dual 2" exhaust streams, the effect of reduced back pressure on
performance is dramatic. Just as dramatic is lowered exhaust system
temperature (the only heat shield I run is under the passenger side
manifold). Substituting a gutted converter won't overcome limitations
of the Y pipe, or small tubing diameter, but it certainly is worth a
$50 investment. Do yourself a future favor and install it with
stainless nuts.

Depending on the amount of road time your DeLorean sees, and the size
of your yard, there's a very good chance your lawn mower will actually
produce more pollution...
