Question about exhaust gaskets

[Fab]

Thanks Troll!

I have 150,000 miles on my 1500. I remove the muffler when I change the rear tire (as shown in the service manual) and sometimes I run my Cobra Peace Pipe. Never replaced the goat bladder exhaust seals, just the header port seals

If I have to remove the stock exhaust on a 1500 (everything, including the goat bladder and header pipes), and then put it back, in addition to replacing the 2 header gaskets (like this one), do I also need to replace the 3 gaskets (2 like this and 1 like this one) where the pipes connect to the goat bladder?

Thank you!
