Don't waste your money. If you want a stock looking test pipe, crack yours open, weld a straight pipe in, close it up and put it back on. WAY cheaper than what's listed above.


You seemed to blatantly miss the part about it being for a 2001 or 2002 Cougar though!
I believe even the post header says "Cougar" as well.

They have one O2 sensor after the main cat. None after the pre-cats.

Also $20 for one is a HELL of a lot cheaper then other MIL Eliminators available. (Still cheaper to build your own though)


You are correct that we do not need one when deleting the main converter.


Yes I do agree that by definition a test pipe is a replacement for a converter.
I am guessing they wanted to use the same "terminology" for ease of understanding since they sell test pipes both with & without a cat.
