Does anyone have data on exhaust pipe size as it relates to gaining
HP in/out of our beloved Hudsons?

I am interested in finding out what the different modern pipe sizes do
for my 232.

How do some of the different flow patterns inside the mufflers help/hurt?

FYI
An enhancement to any motor is to install duals with headers. Drawback with headers on Classics that set a lot they rust out, unless ceramic coated, and then, they need maintained to prevent rust out.

A nice alternative is the 7X cast iron dual adapter that bolts to your stock Exh Manifold that BobdrivesHudson from this Forum sells, then install some type Turbo mufflers. 2" Pipes should be sufficient.

I'm afraid the painful truth here is that the exhaust system on the Pacemaker and other 232's is more than adequate for that engine size. Anything you do is going to be merely a cosmetic or an audible enhancement, not a performance improvement. As the saying goes ... "there's no substitute for cubic inches." If you really want to improve the performance, put a 262 engine in it.

Thank you, Park. I was looking at the pipe sizes available to me at the local shop and was wondering what HP gain I might get by going from 2" to 2-1/4".

I know I can gain 3 HP by going to a 6v electric fuel pump. Mr. Albright shared that one with us.

Actually, performance is less about horsepower than it is about torque. It is a given that most any 6 (especially Hudson 232-262-308) will jump a V-8 at the stop light - for a few yards. Not because of horsepower, but because of torque.
