I have an 01 gsr teg I bought for the wife that has an I/H/E. I'm reverting it to stock. I also have an 01 LS swap for my ek while I turbo my d16.

I want to use the header off the gsr on the ls but I read it needs modification. Question is what needs modified??? The gsr header is a comptech usa header.

All I'm finding online is gsr and type r headers are one thing and b16,b18 headers are another.

 

the difference is the length and collector flange

 

Noticed that there are two different angle flanges: one lays flat and ones lays at about 9 o'clock....

can someone clarify which is which?

00-01 gsr has a different exhaust than a 94-99 gsr.

 

The 96-98 gsr is ob2a 94-95 obd1 on my gsr header no o2 sensor both are in cat

 

Can anyone clarify the different flange angles....which years are the flange flat (horizontal to the ground) and which ones are angled (Looks about 10 O'clock)?

Went to the smog place today for advice, and noticed that his 94 Integra Ls had the flat flange.....
