Default Exhaust Question

Will the stock exhaust from a 1992 454(330 hp) work on a 525SC 454? I assume the heads are different but I wasn't sure if they would work.

They will bolt on but I would not suggest it.
They will choke performance and may cause reversion.

They will physically bolt up will cause more backpressure and an HP loss. Also, might run into reversion issues.

I;m sure there may be a slight hp loss. But being a SC engine I would think reversion won't be an issue?
