Exhaust flanges

I’m about ready to get exhaust installed but I don’t know where I can get the flanges for the exhaust manifolds. I bought new trailblazer SS exhaust manifolds and I guess the truck flanges won’t work and the muffler shop says the don’t have them. Any idea where I can get them?

Re: Exhaust flanges

The truck flanges do work with the Trailblazer manifolds. I have those manifolds on my 5.3L and I used the truck flanges from the donor engine ('05 Tahoe) to build my exhaust.

Re: Exhaust flanges

Truck flanges did work. I’ve now put about 100 miles on my truck!
