Hi, welcome to the site. Ok, the mk7 have VVT turbos that NEED the cat left on, or they simply don't work, so only go cat-back. K&N don't make a filter that sits in the std box, but pipercross do, worth about 3hp. EGR blanking can work for better driving on a mk7 but it will throw up a fault code on the dash after about 100 miles. Vantuner on here (Martynx) is very highly recommended on here, he can remap and delete the EGR for you. One thing to remember is the std factory system is perfectly sized for these engines, so stick to the same configuration or you will lose torque at low-mid range, same goes for the cat. If your looking for high gains then speak to vantuner first as you can change injectors and possibly turbos, but price is high (£2k). I have a stainless system on mine, probably gave me about 5hp, but I'm sure I lost some low down torque.
Happy Easter
