I just recently bought a TJ Unlimited (LJ) that has a 4" lift and long arm kit.
It needs a new cat back, as I'm shopping around I'm being told that the exhaust will require "some modification".
I've done some googling and am unclear as to what "some modification" means.

What is typically required for installing a cat back on a Jeep setup such as mine?

Thanks in advance,
