What are my choices for stock (style) manifolds on my 2WD Suburban? My factory manifold cracked when I hit a large bump that broke two of my exhaust hangers.
I swapped in a Dorman replacement that looked almost identical to the factory piece. The Dorman manifold cracked at the collector
I don't think I overtightened the collector. This did not happen until after a few heat cycles. One of the bolt holes just cracked off.
I attached pics of the OE manifold and Dorman that cracked.
I'd rather not put headers on my stock truck. Is there a non Chinese manifold available? Should I just try to find a used one? Should I try another Dorman? Jegs was great on the return, but I don't want to keep replacing this manifold.
Here's a pic of my truck, just because it's gorgeous even when broken
Thanks!
