then what cat do i have??? both are on the cat and there is no bung on the header, do i even have a factory usdm type r header, the exahust and cat def look to be factory civic pieces??

sorry i have a b18c5 motor

 

you'll know if you have a factory exhaust manifold, the four dump high,normal to have a primary and secondary o2 sensor, the primary doesnt have to be on the header, it just has to be able to read all four cylinders.

p.s. just so you know the primary and secondary have different part #'s
is the first o2 bung on the down pipe in front of the cat?
the type r was never available in the us, except integras

 

my primary is on the front of the cat, i dont even have a bung on the header, do usmd type r headers come w/ a bung on them b/c the jdm dc header i jsut got has a bung on it

 

you may, have a gsr header and cat.. 96-00 gsr's i believe has two o2 bung holes in the cat.. correct me if im wrong

 

ok so if it is, is the type r header longer than the gsr??

 

ttt

 

My cat thats off a '98 ex is 16.25 long and has 1 bung.

yes

 

nah i think im a have to disagree on that one but im not 100% sure. also beside the gsr header, which ones come w/ out a 02 sensor bung and will fit on the type r

 

GSR header


if you look where the flange is cut off at, its near the mount bracket.

DC jdm header


and if you look at your DC header, the flange is extended pass the monuting bracket
