maybe this was asked before, does anyone know how much better performance this will give you? if you paint a line on it,and cut off where it stops.curious if someone has stats.



Being that I was in the exhaust lab at Chrysler for
YEARS I played that game... its not a good way to do
it.. just for info.... it doesnt know if the engine
is fat or lean and different colors burn at different
temps... but i you make them 16" to 18" from rhe end
of the primaries you will be real close
