As an engineer for the past 30 years I find it hard to conclude that the
tailpipe size reduction accounted to the improvement in your times.
You changed mufflers to one that is a completely different design and is
considered to be less restrictive than a Flowmaster, you removed the jet chip
that has a dubious reputation at best (seen a number of back to back dyno tests
that would indicate you loose power with it), you imply that you changed gas,
and your two tests were months apart with who knows what changes in
environmental conditions. Other things that come to mind are how much
dragracing do you do? I don't do much and I see over a second differnce in my
times on the same night on the rare occasion that I go. How new were the
tune-ups (i.e., how old were the plugs and how recently had the air filter been
cleaned) at the time of these runs?
There are to many variables and unkowns here to conclude that the size of the
tailpipes had anything to do whith your runs.
