I know this is probably a really stupid question, but does anyone know the size of the nut to go on the muffler? My friend lost the two bolts and I can seem to get the right size. It's a 2000 Cherokee if that matters. Thanks!

 

I can't recall having nuts at the muffler.
Try google exhaust clamps, they are around 5$ at your local store.

 

I believe they are a 13 or 14 mm

 

From the midpipe to muffler there should be two nuts connecting that. Then from there back rest should be clamps. Not sure what size the two nuts are.

 

That's what I'm talking about. Those are what I need if anyone knows the size cause it's really annoying when it rattles.

 

Turns out it was a 14mm. Thanks guys.
