Car Detailing Forums New

While there are no specific guidelines for what actually makes up a 'detail,' it is typically considered more extensive than washing and drying a car.

Random Post Every 5 Minutes

hi all,

on most tri y headers, i noticed pairing of cylinder 1 and 4, 2 and 3 (1-4, 2-3) which forms non-sequential header but i saw some tri y headers have pairings of 1-2, 3-4 which forms sequential header

im hunting for new tri y header but im confused with which one to choose to suit overall street performance output

anyone can enlighten me on the effect of pairings of header primaries on the power curve?
it will be good if i know the difference so i can choose which one is...
