i have a 2000 integra gs and i was looking for a header and ppl were saying to get an ITR header.. so if i got a header offline that said it fits a ITR would it fit my car as well.? like do all the integras have the same exhaust hole patterns or something? lmk
thanks

 

jdm ITR header is 2.5 inches at the outlet. Your connection is smaller.

 

which can be fixed with a 2.5" cat or test pipe. the main issue you are going to run into is oil pan clearance. i have the JDM ITR 4-1 header and it would not fit with the LS oil pan. i had to change over to a GSR oil pan for the header to fit.

 

oh alright thanks.. never knew that
