"Track pipe" is typically a short pipe you install after pulling the axleback muffler so you don't melt all the plastic at the rear of the vehicle if you run you car at the "track" without the OEM muffler. After market exhaust system parts come in several configurations: Axle back, cat back and header back. Some OEM compatible, some proprietary. O2 sensors are located on the header with the primary cat. Removing the 2nd cat will not affect the O2 readings as there is no sensor downstream from it but, in some states that will get you in trouble as it is a violation of federal law. In California, they enforce this and you can get fined. I'm thinking the 2nd pipe (w/cat) is what you meant and the term for that pipe is "test pipe", "frontpipe", "downpipe" or "high flow cat (HFC) frontpipe/downpipe".

Correct but, midpipe is the one with the resonator.
@
Hotsaucze...here's my current set-up....
MOTIV over pipe and high flow cat front pipe, both with some exhaust wrap to help cut down on Texas summer time heat under the hood:
Some say the overpipe does not add that much HP when added and dyno'd but, when you see the OEM overpipe without the heat shielding and all the indentations on it...why not?
Perrin "cat back" resonated:
Anyway, I'm just about ready to see Joe at Dynotronics now!!!!! Santa's got me tapped out right now though.
