OEM cast iron exhaust

[sam z]

Ok...part II of exhaust drama.

Is there a significant difference between HP and Non-HP exhaust manifolds.
Significant is the key word here. I'm not sweating date codes and "stuff" like
that. More restricted? Outlet size different?

Thanks,

Yes. The log style or non HP do not flow as well. :cents:

The non HP exhaust manifolds are real restrictive. I wouldn't even pay money for a set of log manifolds for a wheel chock.

Got it men...thanks.

Haven't jumped ship on my headers yet, just looking at option B in case
there's a need.

Check with Gary; he's been known to give them away as Christmas presents... :basketcase:
