I have never heard of an exhaust leak causing "ticking".
A. Drain oil into clean pan, check for fragments of spun bearing. SIMPLE ENUFF!
B. Cut your oil filter open using a dremel or cutting wheel, check for bearing fragments.
C. Depending on results, check valve clearance & or pull oil pan to check oil pickup & rod bearings out...
Simple enuff.
