Ok, I just recently learned what WHP means
And I want to know is that how the HP is measured when you buy a car, ie the 180 hp that the GTS comes stock with. So if I were to add a TRD
exhaust with a 6 whp gain (correct me if I am wrong on that number) would that only increase me to 186 or are they compleatly different, or is 6 a big difference. Please help
or let me know if just confused you, either way.
