GUys....
97 ITR motor in a 94 ls...was running stock itr headers, they broke....can i replace them with either gsr headers or si headers....which one is a better fit till i can upgrade....thanks.....

 

Well, to answer your question, neither will fit. The length of the pipe that runs under the car on ITR manifolds is longer than all other b-series, because they have a different catylitic converter. Did the manifold just crack, or what?

 

yeah...my buddy hit a pot hole and smashed the damn header flat....i have a si and a gsr header laying around and i wanted to use one till i can buy a new header for the type-r.....will either header bolt to the head...cause i can run the stock ls exhause till i can replace the typr r header....

 

Yeah, I was talking to some people tonight, and as it turns out, LS manifolds and Type R manifolds are the same length. Si and GS-R are shorter.
