Exhaust Manifold Options

Damn! Hopefully I have better longevity than that.

Great thread. I was planning on BBK shorties if something ever happened. Not sure if that would be better than stock or not.

What about flowtech?

I was also thinking of going with headers if mine ever cracked but if they give similar problems, I think I may just stick with factory manifolds just for the ease of changing them out vs headers (ie bolt access).
 
My truck is having both replaced under warranty today (2019 / 58k miles). Has anyone had the new parts crack or are they holding up better?

It's too early to tell. The redesign was done less than a year ago.
 
I replaced my cracked stock manifolds with JBA shorties and now the JBA header on my passenger side has cracked and sounds worse than when the stock ones cracked. It's so bad, I can hear the tick while driving on the expressway. JBA has agreed to replace the cracked header, but I am going on two months waiting for the replacement. I feel like I'm driving an old beater. It's embarrassing to drive it like it is.

I've seen BBK, JBA and even AFE have issues.

Headers have been around so long and yet they still have issues like cast manifolds. 🙄

People seem to forget the abuse these things endure between heat, getting rapidly cooled from a hot state if you run over a puddle, numerous heat cycles, etc.

I rarely make an excuse for Mopar but it seems to be a running theme among so many manufacturers. They all seem to eventually go.

Yup. My `97 Expedition`s finally rusted out in 2016 with 240k miles on her.
 
Just a quick update on this issue. It took two months of waiting, but JBA sent me a replacement set of headers. I only asked for the passenger side, so I feel like they went above and beyond. Now I just have to find time to replace the cracked one.

Glad they sent me both, as both were cracked. Getting pretty good at doing a header swap on this vehicle.
