Driving home on the 101S and saw a Subaru with a pipe looking thing apparently attached to the exhaust. Then some wires or hoses running from said pipe thing into the rear passenger seat. It looked like there was a big black box in the back these hoses or wires ran into. There was also a black thing on the gas cap or in place of the gas cap. Never seen anything like this before.

No clue. Maybe a Jack Kevorkian "DIY" kit?

My guess it's some sort of smog analytical device or the person is trying to commit suicide...

Some kind of test car measuring exhaust emissions?

Modified Flux Capacitor

Flux Capacitor.

It's an adiabatic homogenizer ala Smokey Yunick.

It’s a Borg-mobile

The owner was caught running non ethanol fuel and creating too many hydrocarbons by CARB, he is now forced to breath his own emmissions as a penalty for warming the air in CA....

Haha my first thought was suicide, but when I got along side it, it appeared to be two guys in button down shirts talking. Flux capacitor would be fucking cool, but no Doc or Marty inside. The license plate was a CA plate, DST down the left side of the plate, 18593 across as the main identifiers, and what looks like 26B down the right side of the plate. My guess was measuring emissions, but not sure why on what doesn't look like a new car.

Haha no only doing 65, no blue light with them shooting off in a fire trail...

the Ex-Bomb attachment?

Oscillation overthruster.

A non-reversible tremie pipe to the differential girdle spring on the “up” end of the grammeters.

That is the modern version of the old PONDO device (developed by Volkswagen for the air cooled engines)...it recirculates the exhaust gasses into the PONDO separator where hydrocarbons, especially carbon monoxide are converted into oxygen at a great loss of temperature...the oxygen released into the inside of the vehicle can be 23 degrees cooler than outside temps...sort of a exhaust powered "air conditioner"...they have been around since the early 1950s...I haven't seen one in use for years.

A variation of one of these contraptions

Nismo has it right. The mobile FE measurement device is used more and more these days. Chassis dynamometer testing is more precise and more accurate, but real world measurements are of interest.

So likely an emissions device. Pretty interesting and very odd to see. Those emissions devices look a little more intense at that link, but if it is, guess they moved a lot of the stuff inside the car.

Looks like a veeblefetzer.

That was the original name of the PONDO device IIRC...the name change was due to using redwood chips in the device here in the states
