In one of our storage sheds, I found an old 1974 (early) oem exhaust. It has been in the rafters since 1975 or so. My dad bought a new 260 and in short time, swapped the carbs and exhaust. I test fit it and it fits well. I need to source a chrome tip and a couple of hangers. 

I am thinking of painting the rear exhaust and resonator black, but I cant decide if I should just clean the pipes up as best I can, or hit them with some silver. Or should I keep the header pipe and scrap the rest? I think it would be neat to have an original exhaust, assuming the entire inside isnt completely trashed. Any thoughts? 

 

 

Have you given it the shake rattle and roll test. Good chance a lot of the internals of the mufflers have come apart.

Yes, it had some debris fall out. If nothing else I can use the system as a template to have a new one built. I will probably give it a try and see what it sounds like. 

Not sure what direction you’re heading with your project, I can tell you that increasing the diameter up to at least 2” makes a difference in performance. These engines like to breathe. Just my 2 cents. I encourage others to chime in.

I know the orig 240z is a Nichira. Is this 260z also from that fabricator? I should say: "Nichira" big on the rear muffler.

The orig 240z exhaust didn't have very big diameter and could profit from bigger ones, i don't know but did the 260z have some bigger diameter exhaust pipe? (also is the partnumber different? i do have fiches but no reader present sadly..) 

Here some pictures from a original 240z exhaust (rear part) last made in 1999! (for as far i know!)
