Got the Magnaflow (made in SoCal) on order for the 2.0L #19438 Stainless Catback which is a free-flow design including a resonator and dual-exit muffler, which others I know are happy with. Fairly quiet for street use. Similar to the Magnaflow axle-back versions but comes with the said resonator tuned for the engine and extra pipe for JLU (which I won't use in my JL). Looks to be a great design to me. I'm familiar with Magnaflow already since I had installed their X-pipe 2.5" stainless dual exhaust into my '67 Mustang Fastback which is decently low in decibels and low in rumble to make 92dB sound checks at the track. The free-flow design should increase power in the Jeep just as it does in the car, and sound great, too.
