That muffler may be fine in the South and West but it won't hold up to road salt.
I replaced my stock exhaust last winter with a stainless system. The header pipe, cat and muffler were off the shelf Magnaflow. Fit was OK but not perfect. Tailpipe ended up being custom stainless in 2.5” (stock was 2.25”). Sound is great but that really depends on what you like. Stock was overly quiet for me. I think a straight six sounds amazing so I like to hear it. Definitely not loud or obnoxious though. Has a little burble between shifts and on deceleration around 1500-2000 rpm. One thing though: the system is less restrictive than stock which seems to rob some low end torque, so if you are staying with a stock motor, keeping the pipe diameter stock is probably better. I’ve read this elsewhere and seen it myself on other vehicles. Upside is more power and more freely revving at high RPM but prob not relevant for a Jeep, unless you’re mud bogging.
