    Milltek make a resonated (quieter) system and a non-resonated (louder) system for around £700, seems the common choice in these cars. However I've just had MIJ performance make me a system, for around £500, they'll make whatever style and noise you want, worth the trip if you can, they really know their stuff.

    As for 'piggies' i think it's more of an american phrase for gutted pre-cats, emptying the catalytic converters nearest the turbos, allowing easier breathing and cooler running. Also give you a slight increase in power and more noticeably a little more torque.

    Hope this helps ya.
     
  3. I have had my custom MIJ exhaust for a few years. The can make it to your spec and they did 2 100 cell cats for me at the same time, cheaper than a single audi cat for the wole shumonga.

    Should be perfectly fine as you'll still have the main cats

    I've MOT'd S4 with pre-cats removed, and they've never failed on the strength of that...
