I tried to get an exhaust place to modify my exhaust for dual pipes but the man said the air leveling system sensor is in the way and that he couldn't do it. Anyone had dual exhausts installed on their 98 EXPY with tow package (air leveling suspension)?
Thanks,

Where are you wanting the pipes to exit? Had true duals on our '97- both pipes came out at the stock location. But, the '97 had neither the tow package nor LLS.

 

Each pipe is to exit behind each wheel.

You have to look out for the plastic gas tank on the driver's side as well. Not a good object to heat up with an improperly placed exhaust pipe. I would consider spending the bucks and finding a good single exhaust aftermarket system instead. Less chance of a problem caused by bad routing.
