Does anyone know if there is any difference between the 96-98 ex manifolds & 99-04 ones. I know the studs are different sizes. Any hp difference??

I Have PI heads done and the old headers bolted right up. I think it's the exact same thing

When I swapped from the 96 engine to 01 I reused the 96 manifolds & it all bolted up perfect. Just heard a few rumors that they may be different flow wise. I plan on changing them out soon anyway for some Lt's. Thanks for the reply!!
