Can this be done? What would be the hp gain over the crappy camaro manifolds. I would change to some high flow cats if it can be done. I have a picture of the corvette manifolds. The reason why I ask is I believe the lt4 manifolds are extrude honed and stainless. Does anybody know?

 

You would have to mock them up to be sure there were no clearance issues. Custom pipes would be needed to mate to them, since they are not made to fit the f-body chassis.

 

So they should fit, just have to do different piping to get it to the y

 

OP

even after the custom piping to connect to your exhaust....why?

you won't see any performance gain...

just get headers

 

You don't think you would see any gains? I would've thought it was equivalent if not better than the dual cat shortys?

 

no I don't. maybe a dyno would show 1-3 hp, if any gain. Nothing that equates to a faster time

 

Oh than f*** that idea. Moving on lol

 

Please do not test the language filter.

 

Unknown. They very well may NOT fit if the manifold exit interferes with any chassis components.
