There really isn't much difference between test pipes. They really are just straight pipes. Compare the materials used though. Some use better stainless steel.

As far as performance, there won't be any difference regardless of brands. I would consider resonated test pipes, to cut down on the rasp. Adding a resonator in no way effects performance, other than sound.
Thanks! But, some people inclduing Chris says that resonated test pipes give better numbers in performance than the HFCs. Now, I am a little confusing.
