Im designing a header for my 95 ls, but when i dyno my car i want to get some #'s from a VTEC model, are the dimensions of a 95 LS header the same as a 95 GSR? thanks

 

nobody knows, i thought I'd get a response in no time. wheres the vets. at?

 

No, the GS-R is approximately 4" shorter than the LS header.

 

much thanks, looks like i only get 1 test mule, what about say a 99-00 si

 

The '99-'00 Si header is the same length as the LS, though the height is a bit shorter due to the B16A's shorter deck height. The flange that connects to the cat is also angled differently on the LS versus the Si.

 

The headers are the same for a 94-01 LS, 00-01 GSR, and 97-01 Type R.

94-99 GSR's are different.

 

thanks a lot that helpped me out thanks, anybody know a good place to use a dyno in pomona area, the dude from injen said i could use his for a little more than a bill, but he seems busy and i dont wanna bug him
