Answers :

An exhaust donut is basically a lead ring that mates the exhaust headers/ manifold to the rest of the exhaust. to remove it you must separate the two exhaust flanges on the mainifold and exhaust pipe. These are usually held on by a bolt and a nut going through both. after they separate the lead donut wil be between the two. Sometimes due to rust and extreme temperatures exhaust is rather difficult to get apart and may result in broken bolts. Use plenty of PB Blaster (penetrating lube) to help separate these two flanges. Good luck!!
