Will a 99 4x4 exhaust bolt up to my 97 4x4 manifolds thanks

 

I'm afraid we are gonna need more details
GM, Ford Dodge ???
Engine to which Engine?
Reg cab to Reg cab ?

 

I have a 97 Gmc ext cab 4x4 5.7 my friend gave me the exhaust piece the connects to the manifolds off his 99 chevy ext cab 4x4 5,7 will it bolt up thanks

 

When I did a search for a cross over pipe for your 97 ext cab 5.7L it didn't include a 99 5.7L. So I expect it's not gonna fit as you hoped it would. But hey. with enough persistence and ingenuity anything is possible. They both have the 3 bolt mounting flange.

 

Being that the 99 is a 5.7 as well, can I assume that it is a 99 classic? They're pretty rare but they have the same styling and body as the GMT400 pickups (88-98). If it is indeed a classic, then I would be fairly confident that it will bolt up just fine

 

Ok thanks guys I was hoping
