Hey, does anyone know off hand if the B series Skunk2 Alpha series header (gen 1) and the JDM ITR 4-1 header are the same length?

Reason being, I have 2 integras, a DA and DC with these headers installed and would like to swap them, will this be a direct swap without any modification needed to the cat? Just wanna make sure before I go ahead and start the work, Thanks in advance

 

It may be best to contact Skunk2 directly for that information.

 

Rarely will you find an aftermarket header like the Alpha that you can bolt on with a cat. In fact, I can't think of a single on off the top of my head, I don't even think the real Toda bolts up. You will probably have to have a shop modify the B pipe south of the cat to get it to fit, or you can always run a test pipe. Seeing as how the header is not smog legal, I'm sure you're not concerned with passing smog still.
