So i have what im guessing is an exhaust leak, i have already replaced a bolt in the exhaust manifold, and that quieted it, and i realize it may need a new gasket, but i believe that the loudest part is coming from the exhaust "doughnut". what i am hearing is a fast paced ticking noise. it sounds like its coming from under the cab. if it is the doughnut is it a hard fix? or how much would it cost to get it fixed? all answers appreciated... thanks!

 

i had the same issue..new doughnut should fix your problem..only around $10 each

 

It's not hard, but a pain in the butt. Had to do it to my dads 08 vmax 3 times.

 

i wanna know where you got yours for 10 bucks, i paid 17 bucks a piece for mine before i even thought about putting headers on it. but it's pretty easy to do
