Easy - less restriction, more power. I gained about 10 switching from a HFC to a test pipe - on my 8. On my X, i am running a one piece with built in HFC.

Disadvantage...emission.

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.

I only noticed some smell...nothing bad. Then again, I've lived in Korea for 5 years...that place smells like kimchee and ass smear.

The sound is a lot louder though...very noticeable at WOT. That would be my only complaint.

What's Germany like with car inspections/registration? I hear the UK is terrible with it's MoT or whatever regulations.
mate germany is a car modders hell!! for every MOD it needs to have a TÜV approval cert that you have to carry in the car at all times and produce at inspections.

UK... is much more relaxed. The use the common sense method, if its not dangerous, too loud etc.. then theres no problems.

I much prefer MOT anyday over money grabbing TÜV. do you know carbon fibre is banned in Germany?? there are some exceptions, but they cost the world.

Ah yes, didn't see the Germany thing. I guess we're lucky to have it here!

The build up from a test pipe does get annoying, but I found my wheels were dirty often anyways so I washed my car often enough to keep the rear clean.

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?
