If I had to do it over again, I would just go with a high flow cat. The benefits of the TP over a HFC is minimal and you don't have to deal with emissions/inspection headaches, not to mention the gunk that will build up on the trunk lid and under spoiler.
1. Running test pipe, no "gunky buildup" in back even though my car shits black smoke like a diesel pickemup truck when I go WAAAHHHHT (WOT)
2. There is a noticeable smell at stop lights, and it is not fuel, it's noxious gas. No bueno. If you have a headache for whatever reason, this smell will worsen it.
3. Noise... the noise is just slightly louder from HFC (went from AMS HFC to AMS non-resonated test pipe) and the note changed at WAAAHHHHT to where I could barely tell the difference when wide open, but if there's a car next to me or a wall next to me, it's a very weird raw noise. I'm indifferent about it but I have yet to hear what exactly it sounds like from someone else's perspective.
4. Fuel economy? Uhhh... how could it worsen? Secondary O2 sensor has absolutely nothing to do with it whatsoever. The secondary O2 is merely a system check for emissions to ensure your cat is doing its job, it has NO input or bearing on fueling. You're also decreasing the back pressure, opening up for better flow. If anything, fuel economy rises slightly, no?
