Has anyone heard of this?

That dyno chart of a Maxima on that listing looks like a chart for a Cattman
Ypipe ! Sorry but bogus ! Plus the chart is for like a 95 Auto GXE Max, even
a auto 01 puts down more- I personally put down 186.2WHP (222HP at crank
stock) bone stock... and there aint now way an auto Max is going to loose
THAT much more HP compared to a 5spd. Cattman headers- 38WHP gain at the
wheels is a better buy for me :)
