LGM vs. Kooks headers?
Has anyone done a "same car, same day, back-to-back comparison" of these header systems?
I have Kooks 1-3/4” with high flow cats and a 3” X-pipe on my ’02 Z06 and would like to know how they compare to an equally sized system from LGM.
To keep this thread from becoming a flame fest, (like most threads comparing one brand to another), please, no personal “opinions”, just cold hard facts with dyno sheets.
