Replace exhaust?

Well I discovered that a rattling noise is coming from my there a better way to secure it? It doesn't seem to be lose or rusted. Am I better off replacing the exhaust? Should I go with a shorter pipe? Any ideas/advice would be great. Btw its a 98 tj SE 2.5

Crawl under and find out what is rattling.

On my '99 the muffler was cracked at the clamp, so it was sliding back n forth making a gawd aweful racket. I cut the mufffler out with a sawsalls and welded back in a Thrush Welded (with a small pipe extention). Total project was about $40.

Ya crawl up under there and feel around when its cool. Broke the mount from the tranny holding the exhaust when I used to have a 2.5 lol. Not sure how I did it but, everything seemed solid. It was rattling the small piece of metal attached to the pipe on the crossmember. Did it really bad when starting or turning off the Jeep. Took me a bit to find it. Pull the pipes around in all directions and jerk them a bit. Go one direction at a time at different points along the exhaust line. For example: Push up and pull down on the exhaust pipe with a good amount of force close to the motor. Then infront and then behind the crossmember. Then go back and do it side to side. Should isolate your rattle

Mine recently was rattling, honeycomb in the catalytic converter had broken loose on the inside, spent an hour, pulled the cat, got the honeycomb out, put back in place with connectors and clamps
