When we put the car on the hoist for oil change , we noticed that one of the exhaust pipe is clean ..

I get one of the muffler shop to cut open the top of the muffler to have a look inside and found out that one of the pipe is blocked off , only there for show .. I asked them to cut the leading pipe inside the muffler and cut open the partitions to the second pipe and now both exhaust pipes works ... this gives me a couple of things ..

fisrt - it excellerates much better , either down low or mid range and revs freer to 6000rpm .. second - it sounds awesome once it hits 5000rpm and yet when cruise it is still very quiet ... thought share this experience :no:

actually there is a spring loaded mechanism inside that opens when enough exhaust gas can push it open. yours may never have worked, or was rusted shut.

if you want a bigger sound, just change the whole exhaust!

Can you take some photos of the inside piping im intrested aswell?

FYI the main resonator under the middle of the car people in the states reckon to swap to the coupe mid muffler... i now own a late model stagea which im pretty sure has a very similar middle muffler setup to the coupe and 350z.... i cant see any reason to change to that pos the piping is actually smaller than the gt8 although the gt8 muffler is enormous so it probably cancels out in the end.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
