All test pipes are a pipe. Nothing special about them. No need to spend over $100 to get one or even with the infamous "CEL fix" gimmick. Just get 1 long anti fouler or 2 short ones and put them between and ur done.

The best test pipe is the one with the same diameter as the collector and catback. I like my T1R test pipe because it is a resonator and looks like a cat.
A test piple in terms of quality is pretty uniform, it's a piece of metal with a claimed diameter. However unless your goal isn't performance you shouldn't have a collector that's as large as your exhaust....
The TP should be Equal to or larger than the collectors, and/or equal to or smaller than the exhaust.
If you have a 63.5mm collector, and a 3" exhaust your TP would make most sense at 3". However it can be anywhere inbetween
