Are there any difference interms of fit or length? How about the 02 sensor? There is one on the header on the 94GSR, how many are there on the 99GSR?

My stock header is jack, so this guy is selling me his 99stock gsr header, but my car is in the shop getting the water pump/timing belt replace so I can't look.

 

the 99 has an extra bung hole in the collector before the cat. the 94 has the bung /sensor on the cat. if you can find a bolt to fit the hole you are pretty much good to go, but i would just put the money towards an aftermarket header(one piece ss is the way to go). good luck!!

i've got a 94 and my a pipe rattles like mad, has ever since about 45,000 miles, i plan to go with a ss header because i figure if i'm gonna spend money on my car it better be an upgrade!!
