Congrats!!!!

Yes, buy a new one. I put one from IAP (I think, maybe Centerline) on my '77 
Alfetta GT when I re-did the engine. New type, replacing the old hatbox. Fits 
as well or better than the hatbox. Better flow than the old pellet hatbox one.

I don't know if it changed the sound or not as I put factory Euro manifolds 
and an Ansa collector pipe in front of it. The sound slightly is different from 
before, but I can't pin the change on any one particular component.

I'm running the standard SPICA unit with my cat and no air pump (shhhhhh). I 
also have a DynoGraph installed, so am trying to keep the mixture at the 
proper level. I've been lead to believe that the lack of air pump will shorten the 
life of the cat.
