Fits my '91 Cherokee perfectly. I laid it out, cut off the old muffler and then put this one in. I used exhaust clamps and Permatex exhaust sealant. No leaks. My jeep is quiet outside now. Not quiet, but don't hear me from the noisy neighborhood. It's quiet enough inside at idle or low speed to hear the hum of my fuel pump, but there's some hum at 35+ mph. Though not as bad as it used to be. Overall, this is a cheap muffler that gets the job done and is ultimately what I wanted for my workโฆ
