Ticking Noise Due to Broken Exhaust Manifold Studs on Jeep Wrangler

Problem Description and Possible Solution

The outer exhaust manifold studs can break and cause exhaust leaks, commonly noted as a ticking type noise. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs).

yup actually i own a 1988 jeep wrangler and have had the issue for many years
Start making exhaust leaking noise when cold, goes away when warm. Back stud broken off.
Been told I have a exhaust leak, sounds like a card in spikes of a bike when cold lose power going up any type if incline.
Front two bolts were gone. Will try to replace them
