My 95 Grand Marquis sounds and runs great. A power increase as well as a meaner sounding exhaust.

This upgrade works best with the addition of a cold air intake system, really no point in doing without either. The open flow can be felt as soon as you mesh the throttle. I would definitely recommend this to someone looking to add some power underunder the hood without letting everyone around you know you have it. Also if you do this with a tune up get ready BC you will have a space craft.
