Modified Exhaust System - Straight Pipe


New member
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.

Do you eventually plan to sell it, and if so, does having them on the vehicle increase your ability to sell it later?

I would like to sell it now but the mileage doesn't leave its value very high. I have 360k miles on it but I have replaced the engine and trans about 50k miles ago. Its worth more to me than I think it would sell for.

At any rate, I wouldn't sell it in its present condition. I will replace the missing components eventually as it hasn't helped performance. (saving money was the only reason I did it)

I did replace the intercooler and went on a 1k mile trip immediately after getting it back from the muffler shop. I have nerves of steel!
