I have this same muffler for my wife's 2002 Liberty and my 1998 Dodge Ram 1500. It is by far the best muffler for your money. Gas mileage was vastly improved for both vehicles. I plan on getting one for my 2005 Dodge Ram 1500 and 2004 Jeep Grand Cherokee in the future. The pipe goes straight through with no baffles - maximum flow and instant horsepower gains.
Good evening I wanted to know if it was compatible with a 3.7L jeep liberty kj Marco
Asked by Marco from Italy on
Hi Marco! Your factory exhaust tubing is 2.5 inches in diameter, so this muffler should bolt right up! I'm not sure how long the OEM muffler is, so I would suggest you measure it before you order this one. You'll need to be very close to the 20" length that the Dynomax muffler is in order to use it.
