I had just a glasspack for awhile. It's not bad at all when the pipping is 2.25", but they do make great resonators. 18" works best, I have it with my Flowmaster 80 muffler, and it sounds great.

Pretty much. I have a dyno vid where you can hear it great. Just look through my threads, I'm too lazy right now. lol

A glass pack is a muffler. It's just a name for a type of muffler that uses fiberglass sound dampening material. If you use a glass pack along with a magnaflow, then you are using two mufflers on the system. If you find a small enough glass pack, you could put it in place of the resonator.

If you use it as a res, ( a small one) will it hurt performance?

Depends on how the gas flow is routed inside. If it's not straight through, it could slow down the exhaust gas a bit. If it's bigger than stock piping diameter though, you might not lose a lot. It all depends. I was using a magnaflow XL straight through muffler for a while in place of the stock resonator. Later I ended up getting a smaller vibrant resonator instead 'cause I wanted to save weight and stream line it in the air flow under the car more, and I took the magnaflow and put it on my grand prix. :D
