what is the difference between the 94-99 header and the 00-01 header for a gsr
optauto.com is haveing a good sale on the header but not for 94-99 gsr
its the stainless 4-1 from dc sports
how different is it and will i be able to make it fit??

 

you can make it fit. your exhaust might just need to be extended a couple inches or shortened... i forget, but yes, you can make it fit relatively easy.

 

Are those mods in your sig already on your car? Do you already have the header? Or is that your wish list?

 

the only thing on there that i dont have is the header and the fuel rail b/c i was skeptical on which one to get
i havent had a chance to order it b/c i m not old enough to have my own credit card so i have to get my dads
but i m kind of glad that i waited now
i just wanted to make sure that it fits

 

it will fit but like stated earlier, it won't line up with your exhaust piping/catalytic convertor so you will need to go to a muffler shop and have it extended and welded up.

depending on how great of a deal the other model is, you might be cheaper to just buy the correct one... some muffler shops aren't very forgiving.

 

If you already have the Greddy exhaust and still using the stock cat, just get an aftermarket cat that's the correct length to match up with the header.

 

good call
yeah i was gonna maybe get an after market cat too
the deal is 180 for the stainless 4-1
best price that i have seen
