Hi I just did a new exhaust new manifold front pipe removed cat flowmaster 44 and new tailpipe it sounds good except for a wierd chirping/squeaking sound coming out of tailpipe. Does anyone have any idea what is causing this? All help appreciated Ty xstreem72 Wyoming

 

All clamped together tightly?

Take it for a ride and then see if there are black spots where exhaust is leaking.

 

I just torqued the heck out of the clamps and going for a ride Ty for the replies.I checked all over YouTube and forums I heard 1 XJ on youtube with same sound and apparently he didn't notice or care

 

Get it good and hot and go over the clamps again.
Might be a characteristic of the muffler....

 

May be more likely that rear tailpipe hangar.
