HS Headers

[Andris Laivins]

>>> Will the 97-99 HS headers fit a 2002 G20?

 Any header made for any car with the SR20DE will fit any other car with an
 SR20DE.  Nissan uses the same length on the stock exhaust from
 the head up to
 the catalytic converter on every SR20DE to reduce production costs, so one
 header fits all.
 The differences come after the CAT to accommodate the needs of
 each individual
 chassis.<<<

Pretty close. They are all interchangable except the 2000+ models.  Those
have a different secondary with an extra O2 fitting and a hanger like the
stock one.  They also lack a fitting on the primary (AIV) . 99 and older
headers ship with an AIV plug for cars without it.   I'm not positive if the
2002 G20 shares the same secondary as the 2000+ sentra SE's  - look under
your car. If the secondary has a second O2 sensor and a hanger, order the
2000+ header.
