I haven't reallly had a chance to have a good look under the wagon (no garage or driveway) until today. I was just adjusting my side skirt to make it fit a bit better, and stuck my head under the car for a good look.

Everything is really clean, no damage, scratches, etc. Then had a look at my exhaust.

It look like it is 3" all the way along. Is this standard? I know it has a NISMO rear muffler, so was wondering if the Japanese owner also replaced the system.

It doesn't look new, and it looks professionally done (ie no crappy welds).

Any ideas?

P.S. When I bought it it did feel a little more responsive than the other Stageas I tested. Could this be why?

2.5 is stock. And stock unit will prolly have 'calsonic' stamped on it somewhere.

Also the stock unit will have three rubber weights attached at various points along the length of the pipe to help eliminate vibrations.

So if it is 3' with no harmonic balancers, then it def aftermarket, and will do lots for your power.

Check the dump pipe leading up to the cat - is it a different size?

If the same, the you're in luck and someones done the expensive work for you.

If not the same - ie the front half upto the cat is 2.5 inch then getting this enlarged along with a 3' cat will do even more for your mid range grunt.

P.S If the exhaust is stock it will be so quiet, at some stage since buying it, you will have tried to start it only to find the engine is alread running.

No rubber weights anywhere on the exhaust, some on the back of the trans and rear suspension mountings.

Measured pipe, it is 2.5" all through.

Rear muffler has 'NISMO' stamped on it as well as 'Calsonic'.

You know when the car is running. It makes a deep, but still quite soft, 'burble' at idle. It sounds nice, not too loud.

So maybe non factory, but not top performance replacement.

No idea, never done it.

Cut it out, flange off the ends of the cutout and the exhaust, and get a flanged straight pipe put in. If it makes it too loud, put the mid muffler back in. If its too quite still, well, at least you did something.

Thats what i am tempted to do, its is a bit too quiet, but its still not horrible or anything.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
