This is an AXLE-BACK system, a CAT-BACK would 99% use a mandrel bend over the rear.
Sure it will but I don't want a loud exhaust with drone which that will have.
The elimination pipe sure does. How many resonators on a JL have you seen destroyed on rocks so far? Ran the Rubicon with this system, no issues at all. If the bulky stock rear muffler was still there, that would be a different story all together.
