Well my first tank came to 37 mpg, 489.8 miles and 13.1 gallons all city stop and go driving. I filled it like the last time until you could see fuel in the filler neck(13.1 gallons) but then was able to put another gallon in it by pushing the vent button that I learned about on this forum I also bought some stuff to build a 2.5 exhaust for it, I'm thinking that will get me over 40 mpg in town. That cat with 2 mufflers has got to be restrictive. Also I'm gonna have to come up with some kind of drink holder for my morning coffee, what have ya'll done for drink holders?

Also I'm gonna have to come up with some kind of drink holder for my morning coffee, what have ya'll done for drink holders?i use a cup/vacuum bottle with a button on it.. no liquid comes out (even when on its side or upside down) unless you push the button..plus, the vacuum bottle keeps my coffee warm for half the day!everyone else uses ford taurus cup holders..and whats this button you speak of? my mk2 dont have no button in the fuel fill spout..it did start out life as a gasser tho, maybe thats why i dont have the button.should get better mileage as well.. mine did a pretty regular 40+mpg (closer to 45 actually) even with a close ratio GTI trans installed..ive since installed a long ratio trans, and have not since checked my mileage.. i got 600 miles to a tank pretty religiously, even with the close ratio trans..
Just delete the cat with a straight piece of pipe. Leave the mufflers alone. Two exits are half the flow to each side. Less restrictive not more. If you use the GPS to figure out the difference between speeds than you should be able to run with it for a while to determine if the odometer is off as well. Generally that is the case. GPS says 37 and speedo, Not the suit, says 40 40/37= 1.08 or 8% off. If the odometer is the same then you are figuring more miles for mpg than you actually drove. 100 miles would actually be 92. I have mine dialed in and it is 6.372% off. Roughly 6 more miles on a 100. So when I calc the mpg I have to add to the odometer ones. Then divide by the gallons to get it correctly. My coffee holder is my hand or between the Ebrake and Passenger seat. Find the right insulated cup and it fits just fine.
Wait a minute? Inline mufflers? One pipe? Ecodiesel? Something isn't adding up here with the cat in line. On the diesel isn't it a resonator that is in there first and then at the end of the line a muffler. All run through a skinny straw line exhaust pipe? Maybe a picture of the system will clarify. I thought you had the gas motor until I went back to the pictures initially posted and see the engine bay. Not sure what to say now.
