Are the muffler mounting locations on a 240Z the same as on

a 260Z and 280Z?

I knoe the diameter of the pipes are diferent but like to

know if the mufflers bolt up the same way.

yes it is.

Here are the changes made up to and including 1975. I only see 1 mounting change. In the first illustration, the mounting points are C,D&E. For the 1975 280z, the forward mounting © was moved from the center tube to the front tube and was mounted to the transmission. I haven't found any info for the years following 1975.

From what I've read and seen, there were no other changes after 12/74 through the end of 280Z production.

Any diagrams for the S130 280zx?

A Cat wants to know if my ANSA Twin Stacks muffler will fit his

1981 280ZX 2+2 on ebay.

I like to give him a correct answer, seems like it would be no problem since the

ANSA's for the 280ZX's in the old cotologes don't seem much different but

they do seem to look more designed for "quieter" operation IMO.

the mounting and layout described in those images are exactly the same as the mounting/layout on my 78 280z, which is the original exhaust that the car came with (muffler is stamped 6/78, same build date as on my vin plate)

so I don't think they made any other changes after '75

That's what I said:

Here's a couple of 79 ZX exhaust system diagrams, California and Non-California. They're the same as an 81 but my 81 manual isn't good enough for scannig:

Thats what I was looking for.

But am I correct, in looking at the ZX scan, that the ZX exits on the right of the car as

opposed to the left side as on S30's?

Evidentally.

The turbo models exited on the left side, as did the later NA models, though I don't recall which year it switched.
