I have compared and researched all available mufflers for my 95 YJ 4 Cylinder engine. I have a fabric top all year round and I'm tired of all the noise on the track, but I didn't want to part with a hoarse deep sound. Also, I didn't want to change the muffler every few years. It was related to this Walker 21200 stainless steel or cherry bomb muffler, I heard it sounded good. The stainless steel and the smooth running convinced me. The Walker 21200 specs are wrong on some websites regarding the intake location. The overall length is 19.25 inches. The intake port has an inside diameter of 2.25 inches. - transferred. It fit perfectly and was nice and quiet on the Autobahn. UPDATE: 9/13/21 - after 6 months of driving this muffler is excellent. Now it sounds even better as the sound is a bit deeper and throatier. I don't know exactly how to explain it, it's not quiet like a Toyota or loud like a straight pipe, but just right. To my ears, the only sound I could equate it with is somewhere between a WRX and an Abarth, if you put it down, it's still a 4-cylinder after all.
