"...go for one of the other exhausts like Magnaflow or Flowmaster. I pretty much got what i wanted. I wanted to be able to hear the exhaust but without the uncontrolled constant roar throughout the RPM. With Gibson you have that control. When you wanna hear it, lay on it! If you're just looking for an increase in MPG's, I don't think this one's for you. I may have rec'd half an MPG increase. But of course i've only gone through about 250 city driven miles, so I may be wrong. I need a highway test really. As far as the quality, it is just as impressive as i'd read. I'm sure i'll never need another catback. Hope this helps someone." —Michael C from Houston, TX bought a Gibson Exhaust Systems for a 2003 GMC Yukon, 5.3L V8.
