What is a test pipe ?
a test pipe is ok to swap in at the track, but its illegal for driving on roads (plus it pollutes a lot more). For daily driver use, get a nice aftermarket cat, if you race enough to make it worth it, get a test pipe, but don't drive around town with it in.

I have a test pipe and its great for turbo cars. It doesnt smell that much, but is really loud. And if you use 550cc injectors you occasionally spit fire out your exhaust.
