No, I did it at a shop. I installed Kooks headers with catted pipes + Borla S + Radium Sparks + tstat + Bwoody CAI

Eventually the sensor is hitting the mounting of the gearbox, loudly and this is what's driving me crazy. Feels like someone is knocking from below.

Sound inside the car, from Kooks and Borla, is great if you consider it for daily drives and its as awesome as it gets from the outside. A friend of mine was installing meisterschaft full system at the same time. My opinion is, the meisterschaft has an aggressive and loud sound, however, it's "raw". What I mean by raw is that it doesn't have any distinctive tone to it. It's just LOUD and UGLY. However, with the Borla and Kooks, I got a medium sound (louder than I expected) but it just amazes me.

Another friend installed Corsa + American Racing Headers. He also installed what the shop calls "butterflies". He got the closest sound to manufacturer, only louder.

Butterflies are gates/valves that they install just before the mufflers and you can open/close them with a switch. You can't go over 20/30 mph with them closed, they are used to pass inspection and cops (almost zero emissions )
