tooter's exhaust experiment...

[tooter]

Up to today, all of the before and after tooter intake manifold dyno runs were with Garm's MagnaFlow center exit exhaust installed. My wife wanted her car a little more quiet, so Scott sold me a nice stock Toyota axleback exhaust, and I put it on the car. It seemed to me to run just fine, but my wife who drives the car more said that it seemed sluggish.

So I got curious enough to do an experiment today, and took the car down to Harry's dyno shop at 15020 Oxnard Street in Van Nuys. (818) 908-9650 It's just East of Sepulveda Blvd. a few blocks.



We did a couple of runs with the only change being the stock axle back exhaust, and there was quite a difference. The difference between summer blend and winter blend accounts for some of the difference, because my gas mileage drops about 2 mpg in the winter. But even disregarding that it still made a considerable difference.



Needless to say, I put the MagnaFlow back on today.
