OK, i searched the threads, and im hoping someone has a spread sheet memorized.

that can help me out with some info here.

I have an L26 in a 72 240.

E88 head

with E30 exhaust manifold.

I ordered the msa premium exhaust system for stock header:

SALE! MSA Premium Exhaust System, 70-72, 74 240Z-260Z (For Stock Manifold)

Code: 15-6302

but the flange on the manilfold and the flange on the new exhaust have different stud locations

whay gives??

Either MSA sent me the wrong exhaust piece by accident,

OR

This exhaust manifold i have is for a different year.(this info i cant find on forum search)

can anyone help me out with wether or not the E30 manifold came on a 70-72,74 240z-260z ??

I can easily send some pics if that would help out.

thanks for any help folks.

all fixed up.

wrong downpipe sent from supplier.

E30 is stock exhaust manifold.

word to note, my shop manual says all zcars prior to 1976 had round exhaust ports and after 76 they were all square.

thanks to willoughby z's link. i see this is definately wrong.
