NOOB 2.0t catback question
 

I have had turbo cars before but never one used a DD. I own an 06 Audi A4, for 3 months, it has AFE panel filter, Unitronic Stage 2 HPFP, KMD HPFP, JHM test pipe hooked to stock exhaust.

I know a complete exhaust may not net much power. I like CTS catback and asked them what they think power increase may be but they have not answered me yet.

Beyond possible power increase if any. My question more about turbo health. No doubt at WOT I'm pushing my K03 to 90%+ of its capability. I know improving intake and exhaust restrictions can help the turbo operate a little more easily. I want to ask those that know a whole lot more if they believe that an exhaust like CTS turbos could help keep the turbo healthy for longer?

I love the car and very happy with current power output. I would like the car to last a very long time and will do about anything to help improve the car in that manner. I kinda wish my exhaust system was a mess but mechanically it was very well taken care of by the previous owner.
