Exhaust popping (exhaust leak?)

[Winks42]

My exhaust has always popped a little on deceleration but researched that was normal but now im starting to pop on idle a little bit. PO did some weird exhaust work before I bought it and I wonder if its leaking from there. I just wanna see if the sound sounds like an exhaust leak. Thanks

Have somebody hold a wadded up rag in the end of the tail pipe at idle while you are under the Jeep checking for leaks along the exhaust. If there's a leak, you'll find it quickly.
