There is a flex pipe on each one, and i forgot to mention the minor hissing noise you get when you are release the throttle at a low rpm.
It fits about as good as any other test pipe out there.
Just know that there is a likely chance your cel light will go up and stay on, there is a trick to putting spark plug foulers in the 02 bung to help 'trick' the sensor, but that only works sometimes.
