Exhaust manifold output size

[dodgegtdart68]

I'm in the process of just getting my 12+yr project on the road n driving. Having exhaust issues n what I have that will work is a 2 1/2" outlet on the passenger side and a 2" on the driver's side. Will this work ??? What issues am I gonna have ??

It wouldn't be too hard to open up the smaller one 3/16" -1/4" or so, just be careful???? Pics of the outlet on the 2" would help a lot!! Don't remember seeing a 2" driver's manifold for small block??????

Are you measuring the outside of the "cone" or the inside of the opening?

2.5 sounds HUGE for a small block...

Sounds like the driver side is maybe 1-7/8?

To the OP (@dodgegtdart68), are these magnum manifolds?
