[Shotimes] true dual exhaust

[Donald Mallinson]

The dyno that Borla used at that time was one that has since 
been documented as giving out false readings to many 
companies.  This was before the popular, accurate and 
affordable Dynojet chassis dyno.  Chassis dyno's up to that 
time could be made to give just about any result the 
operator wanted.

This one dyno shop did a lot of work for Borla and other 
aftermarket companies and has since been found to be giving 
false high readings.  This had the effect of having other 
companies selling hop-up parts to come to them for a "good" 
result.

No exhaust system is worth 30+ HP on the SHO, or almost any 
other car.  Some very high HP vehicles can benefit from 
custom exhaust more than others, but 30 from a cat back only 
is just about impossible.
