B18C1 DC header on B17?

[BigMac88]

Will a B18C1 header fit on a B17? They obviously have different heads, so I don't know the compatability issues there. But also would it fit in the engine bay/fit to the cat propler?

Thanks in advance

b16,b17,b18cR have the same bolt pattern... GSR is diff. I believe the bolts on the end are the ones that makes the difference here...

It will bolt up to the engine and clear the oil pan. As far as lining up with the cat on a G2, that is highly doubtful.

All B series have the same exhaust manifold bolt pattern. Some are just shorter due to the smaller deck height and more shallow oil pan.

How else would everone be putting an ITR header on their GSR? It's just the intake manifold pattern that is different on the P72 head.

Thanks guys! I really appreciate the help. A friend wants my DC 4-1 but he live a while away and is in the Navy so we don't have time to do a test fit, so this info has been invaluable.
