I was told by a muffler shop that if I went with an off road pipe on my car even with the MIL eliminators, that down the road later on that it would cause some serious problems with the car and/or computer. Anyone have this problems? How long have you had your off road pipe on your car?
If it is done right it is no problem. Sound like thet did not know how or did not want to do it. Many muffler shops cannot touch offroad stuff and many others would rather not.
Best to knock out the install yourself... Use lots of PB Blaster, let it soak in for a long while, you'll be fine.
