Small Block exhaust
Ok Guys,
I am looking to upgrade my Engines. I am looking an some good exhaust systems. Anyone have any experience with Hardin Marine stuff. How about the Eddie Marine stuf or the Revolution Marine stuff.
Any comments will be helpfull.

Small block exhaust
You've got a few good choices.
I have experience with the Imco powerflow exhausts and I like them a lot - I think the castings are a little nicer than the eddies, but the Eddies are a bit cheaper.
Ive got the polished powerflow setup on my 406 and it breathes pretty well- and looks great!
I don't know the Hardin Marine Stuff but Ive never heard anyone trash it.
The highest performing setup is probably the CMI true headers.

Stainless Marine
The Imcos elbow is bolted to the manifold.
I have heard of SS marine headers having issues with this particular area before- Have you had any issues with them?

On the Stainless Marine headers the elbow is held to the manifold by a clamp bracket with each piece "fitting" together-

EMI Manifolds come with a five year warranty, and the price is right.

the nice thing about the stainless marine manifold is that if the holes in the transom are not lined up perfectly with the engine you can rotate the riser a bit at the clamp. We have never seen any problems at the clamp area and we install a lot of them.
