I just found an exhaust leak on my 05 durango....pulled the heat shroud and the two rear studs are broken...looks like to top bolt is sheared at the top of the bolt making for easier extraction, the bottom bolt looks like it may have sheared off at the face of the engine block may make for a trickier extraction...however I think I can get at it by removing the pass tire and exaust. It seems pretty straight forward...my quetion is if I'm going to pull the exhaust manifold..... can anyone suggest aftermarket upgrades that might be worthwile..... I have the v8 non hemispherical mag ....its run well except for the clicking/exhaust leak until engine warms up.......makes perfect sense now...also I get a gas cap engine light just changed the gas gap any ideas.....

 

Ditch the manifold and get a set of exhaust headers,
