I have a 96 Grand Cherokee 4.7 L six cylindder and I am looking for some cheap ideas to increase horsepower and speed. I am installing a flow master muffler and having the cat.converter removed (yes I know this is a no-no but congress is overturning that next year anyways).
I heard High Performace chips are just a waste of money is that true?
