I recently acquired a '92 RZ with some nice pieces on it. The exhaust has me stumped though - just can't match it up with anything out there.

The downpipe, mid pipe and catback are all stainless with a heavy sound and look to them. The downpipe has a flattened expansion chamber just after the turbo outlet (99 spec turbos). I have a HKS on my other car this is very different. The head is beautifully welded together, not cast like the HKS. There is no connecting tab at the tail end of the pipe, it does not bolt to the transmission. I found that the car has Mines ECU and I am thinking this might be their system - nothing to compare to !

The mid pipe has a resonator just slightly larger than the pipe itself.

The muffler has the JASMA label with SR on it and code 013, Jieiruto Inc.

Yes, this car has been in Canada and obviously saw a bit of salt.

All help is appreciated !

 

just guessing here... but the catback looks nearly identical to an apexi N1.

 

I would Say N1 aswell.

 

I agree that the muffler looks like a N1, do they have the name etched on the tip? This one does not have any markings. Can anyone confirm that the jasma code 013 would be appropriate for Alexis products?
I have been looking at the rhdjapan Site, the downpipe sure looks like the re-ameniya power expander. Again, no markings.
