Ok I was just curious to see which header will fit a certain integra. Like I know the 94-00 Integra rs ls and gs are all the same and I beleive the type r header will fit an ls. I have always been under the impression that the GSR header wont fit anyother integra is this true. I was told by one of my freinds that the 00-01 GSR header would fit my 94 integra ls. I want to know because I am taking my g/f's JDM DC 4-1 2.5" header off and instead of selling it I might just puthere header and cat on my car. If not I have to sell them. Thanks in advance

 

i dont think your friends header will fit your car, but maybe someone can fully back me up on that

 

00-01 GSR, 94-01 LS/GS/SE/RS and 97-01 ITR headers are all interchangeable.
A 94-99 GSR header will only fit a 94-99 GSR.

 

can anyone else vouch for this because I dont want to start the install and relize it doesn't fit lol.

 

Look at the diagram in this thread.
