[alfa] Resonator replacement ideas

[Jon Pike <jhpike@xxxxxxx>]

Hi all..

I am getting a new cat to replace the 27yr old unit that is a rattly, 
noisy, dead doornail..   I'm hoping that the new one will improve the 
tone of the exhaust, (or at least not contribute so much noise to it!) 
as well as clean it up.

But, "for off road use only" ;-) I have a pre 75 dual manifold, a needs 
some work set of downpipes to fit, (or might get new) and was wondering 
what might go on the other end to connect to the center muffler?

Early cars had a kind of  box that I was under the impression, was more 
a resonator than muffler..  though I think I saw one cut open once, 
about half cavity half muffler like damping.  Anyone have experiences 
with using straight pipes, or small glasspack things there,  and how did 
it influence the sound?

That, and a cheap source of a few flanges,  and I'll be set for several 
kinds of motoring..
