The turbo on my van would turn off after a few seconds of idling. The mechanic determined the intercooler was busted and likely a result of clogged catalytic converter/muffler. I priced these items to find out it they cost approx. $2000 for parts only.
Reading this board last week I found out the van would run without the two emissions items so I decided to take a chance. I have a straight pipe from the turbo back to the original tip. (I live in a test free state.)
The van is slightly louder than normal, possibly a little more responsive and the mpg on a 1000 mile trip was the same as before. (21mpg loaded with 2k lb. cargo)
Eventually I will put an aftermarket converter and muffler on as there is not benefit to having them removed.
