Hey Pat,
       Yes, a single glasspack is going to be loud.  I would recommend a 
free-flow Corvair  or Wagner Turbo muffler for better sound control.  These 
mufflers were legendary back in the late '60s and '70s among the Muscle Car 
crowd for their low packpressure and reasonable decibel level.  I have a pair 
on my '69 Firebird and eliminated the twin resonator/single muffler design 
from the factory.  The sound is reasonable at full throttle.
       For my '89 Spider, I eliminated the center muffler and kept the 
catalytic convertor and an AlfaRicambi rear muffler.  It's on the loud side 
of reasonable.  If you're going with a single muffler, I think you want a 
muffler that is free-flow plus good sound control.  The glasspack satisfies 
the first requirement but flunks the second.  
       Check out the Summit Racing Catalog for several companies that carry a 
Corvair Turbo-style muffler - DynoMax, Thrush, Edelbrock, Hooker, Flowmaster, 
Summit.  I realize these are not names we are used to seeing on the Alfa 
Digest, but stay away from the glasspacks!  You think it's loud now?  Just 
wait for a few thousand miles when you've blown all the fiberglass out.  Then 
you will know what LOUD really means! 

Cheers,
Charlie
