What kind of header are you installing?

FWIW, the Si and GS-R gaskets are the same size.

when i look up the parts they list as the same size but for some reason i've heard to use the gsr one instead of the si ones cause they leak

measure the collector on the header and go to the parts store and get one that size.

i know the collector size, just curious if anyone else has heard to use the gsr gasket on the si's due to leakage problems

as far as I know, SI, CRV, LS, GSR are all the same gasket.. They all take B-Series cats, and all have the same size factory header collector.. the only B-Series doughnut that I'm aware of being different size was the JDM Civic-R and JDM integra-R that have the factory JDM Tubular Header.. the collector is HUGE..

If it is a "USDM-sized" header, an Si or GS-R gasket will work fine.
