I have a 95 ls and i bought a gsr 94-99 dc sports 4-1 header. will it fit on my car? and what about the o2 sensor there is no hole for it on the header and i though ls had the sensor on the header. can i get a hi flow cat with o2 sensor holes and put that on my car?

 

anyone? also if i bought a gsr 94-99 hi flow cat would that make the system work? i'll probably have to get custom b pipe though huh.

 

you've got the right idea.

I believe your car is OBDI so it shouldn't need the extra 02

 

Cool, thanks man.

 

one last question do i have to get new gaskets or can i use stock. The header i bought was ceramic 4-1.

 

If it is going to fit, your stock gasket should be fine.

 

but you might want to replace if you have it removed

 

I'm pretty sure it won't fit. 00-01 GSRs have the same header design as the LS, but 94-99 GSRs are different.

 

No the 94-99 gsr dc sports 4-1 header won't fit your 95 ls w/o modification. You would need to cut/weld a hole for the 02 sensor and shorten or extend the header since a 94-99 gsr cat has a different length. Since you are OBDI one you only have one 02 sensor on the header and none on the cat.

 

ah I had my 02 sensors mixed up
