Thanks Alan, logical explanation about the clamps , and we have nice twin factory's exhaust systems !

Thanks Carl, about the story of the clamps and detailed driving expression. I am thinking I may install it to my Z432 or not.

Hi Jason240z, not special recently, but Santa brought me a new head for Z432 and some presents for my L24.

Merry Christmas

Nice part no. 16500-E4620.

I didn't know there was that heat shield available. I am interested in this set up on my 72 240z.

Hi Gave , if I find this I will let you know. Or some one can make it from a sheet metal. 

Yesterday I picked up my blue 240Z from a museum to have some work . I dropped  my 240ZG there instead of it.

I replaced a battery which I bought in 2004 ! to a new one, it was an amazingly durable battery , when I brought this blue 240Z to the ZCON long beach LA 2004, I visited Bakers field Nissan then I bought this black battery and installed at the dealer. A former battery which was on my car was presented to the dealer . The former battery was like a new at that time but it was white YUASA one , I wanted black battery. 

This time I found YUASA black one, I will decorate like old Nissan wrapping.

And the water system, terribly bad condition in a decade, I replaced hoses and water pipes.

Honda now makee a nice Blue coloured antifreeze for your blue car

I doubt Honda makes their own coolant...probably just rebranded Pentosin Pentafrost NF coolant which is blue.   BMW also uses blue coolant.

Just because the coolant is in a Honda bottle does not mean they make it.  My point is there is a lot of blue coolants available, not unique to Honda.

Hi Kats,

I actually found a pair the other day.

I saved the images for reference so I can make my own at some point. But you are correct they could be made out of alloy sheet.

I may ask you for measurements at some stage.

Kats,  what kind of filter media is in those air boxes?   It kind of looks like oiled gauze.
