witch way to go?

For the most part, a full bodied muffler will make more power then a glasspack with the same input/output diameter in my experience. And i don't personally care for glasspack's. But with that said, i don't know that there is enough difference if you really like the GP sound?



P.S. Just to clarify, What I was getting at on the in/out comment above was, that years ago even with a 2 1/2" glasspack, the core diameter was usually reduced to keep them from being crazy loud. I'm not sure about the ones available today?
