Rated 4 out of 5 by 15 reviewers.
Rated 5 out of 5 by Fit great and very quiet muffler. New muffler was a little smaller in size, but fit great and the truck hardly makes a sound now. Hope it lasts longer than the OEM one. November 2, 2015
Rated 5 out of 5 by Fit Perfectly, Nice and Quiet Old muffler rusted out, was able to easily replace it with the Walker muffler, fit perfectly. My Jeep is much more quiet now. October 9, 2015
Rated 4 out of 5 by Seems to be Ok...... This replaced my original stock muffler. It was very easy to replace, and the only issue I have had was that the clamp came loose even after tightening it as much as It would go the first time. If it comes loose again, I may use some lock tite on it. The muffler itself is very quiet and sounds great in spite of the fact that whoever had the car before I did took off the resonator.

Rated 2 out of 5 by pipe too small for resonator it should have been suggested to replace the connect to my original resonator I had to get a reducer pipe to connect the smaller tailpipe to the larger resonator. May 31, 2015
Rated 1 out of 5 by JUNK - typical aftermarket garbage Inlet side pipe is the exact same diameter as the exhaust pipe- DOES NOT just slip over and clamp like the oem one. Had to weld a sleeve over it to work properly. Waste of time and money - should of just got the oem one ...... December 28, 2014
Rated 5 out of 5 by Installation went smoothly. The real test will be durability and time will show if this muffler lasts 5 years or more. December 11, 2014
Rated 5 out of 5 by very happy as described easy fit I bought muffler and resonator top quality November 28, 2014
Rated 1 out of 5 by This muffler did not fit the OEM tail pipe Unfortunately, the OEM tail pipe ID is greater than the OD of the muffler. The result is that you would need to by and adapter (assuming you can find one that works) and add some after market clamps. I chose to return the muffler an after market muffler made by the OEM provider (unfortunately I can't remember the name, but a local Lexus dealer can tell you). It fit perfectly and accommodated the OEM clamps. It was $20 more expensive though. November 4, 2014
