just installed HS header onto a 97 se-r, motor started making weird noises but only when in gear, sounds like a air is leaking. everything was tightened and done right. engine light also came on after 25 miles or so???
anybody know what this could be?

TIA,

i thought i heard hotshot headers rattle at around 4000rpm...

Sounds like an exhaust leak. Just to double-check:
Pull the code and see what the error is.
EGR tightened on header
EGR tightened on other end
O2 sensor tightened
Re-torque manifold to 35 ft-lbs
Check primary-secondary connection and secondary-cat connection
Did you mess with the intake at all while doing this?

Used good copper gaskets between all 3 places?
Is it a used header?

I know these are simple, but its information we need to know to help.
