Low on power?

[GrayZ]

i really don't know what the numbers should be...but many
agree...they really vary...so with that in mind..my
car is stock except for headers...at it pulled 353.2 at Bowling Green
last year..i have added corsa exhaust..and i can feel a difference,
more pull ..quicker...since...so...i hope the new catback exhaust
raised the horsepower..6 or 7 horsey's ...next up for me...
will be a haibeck tune..gears...and next year..a HP upgrade..
