People learn better when they seek information themselves. The catback exhausts on the Wrangler (typically) replace the factory resonator with a muffler and do away with the trash can at the rear.

That’s how it is in the truck world, but when I posted that, I forgot that the Jeep Wrangler exhaust is behind the rear axle.
