My stock manifold is crap... 195k and its coming to the end of its life. I found a killer deal on a used dc sports 4-2-1 2 piece but it is from a 92 b18a. Will the header bolt up to my GSR fine? Im running a stock cat and comptech exhaust. I just need somthing now to get me by now since my stocker is all cracked up.

 

No. The A-pipe is a different length. You would need to fab up a spacer (take out some material) of some sort between the LS collector and the GSR cat. I can't remember which one is longer.

 

If i remember correctly the ls has a long a pipe because the o2 sensor is in the header, the gsr has the o2 is in the cat so the cat is longer. I am not 100 percent on this but i that is what i am under the impression of.

 

ah werd.. that sucks hah.. thanks for the help.. my search continues.
