will a GS-R header fit an LS?

 

It will fit the head, but the LS collector is longer than the GSR because of cat location. You will have to extend the GSR header and have an O2 bung welded onto the collector.

 

exactly good call shmoo!

 

NOT ALL BSERIES HEADER ARE THE SAME IF THERE FOR A VTEC ENGINE THEY ARE MADE DIFFERENTLY THEN FOR A LS OR A TYPE R

 

not all are the same like others have said... get one specifically for your car and avoid all the unnecessary changes you have to make to a gsr header for it to fit on your car (ls?)

 

late bump... what header will work on a 99 gsr? My friend got a b series header and it wasnt long enough i guess? it doesnt clear the oil pan...

A '94-'99 GS-R header is the only one that will bolt up without any modifications.

 

not even a stock si will work?

 

No.
