"Definite power increase and quieter than the stock cat-back with a Flowmaster muffler I had before. This system doesn't have the flow-choking crimp that the stock cat-back has either which really opens things up. I opted to install it myself - I'm mechnically-inclined having done this and more difficult things on other cars, but this one got the best of me. After spending several hours and losing a little blood trying to install it without a hydraulic lift, I got it mounted but it was hanging low, leaking, and nothing like the stock fit. I ended up taking it to a muffler shop to mount it more solidly (i.e. without clamps and connectors). That was the best $40 I've ever spent - wish I would've done that to being with. Even with nice solid welds it *still* rattles, shakes, and rolls - nothing like the stock fit. Still a worthy sacrifice to get more power." —Kevin B from Acworth, GA bought a Magnaflow Exhaust Systems for a 1998 Jeep Grand Cherokee.
"I installed this on my 98 5.2L Jeep Cherokee. Immediate difference in Sound, Power and gas mileage. instant 4 miles per gallon around town, shifts at a lower RPM and stays there" —Kenneth D from La Vista, NE bought a Magnaflow Exhaust Systems for a 1998 Jeep Grand Cherokee.
