    Looking at their website there are a few choices.

    1. Size, I'm probably going to go with the stock size, or whatever is closest, as I don't want to step down going to the Milltek catback. opinions welcome.

    2. There are two that fit my bill. Sportkat and the Sportkat E-Test Mark. What's the difference and what one to get?

    They will adjust the outlet size at your request if you want to make things simpler since their standard dp size is 2.5".

    I believe the Milltek is 60mm/ which they say is stock sized. I went for the 200 cell as I inhale enough raw exhaust and the flow is likely negligible on these these cars. E certification is not necessary if you're outside of Europe. (still not necessarily needed inside europe)

    I can upload some pictures soon yeah, just need to host them up. I would say it took about a month. I should also note that I live in Germany so the shipping time is a bit less.

    My Zinram downpipes took about a month and a half to arrive. They've been becoming popular amongst the RS4 driver community, so I think it's taking more time to get the pipes.

    How is everyone liking these down pipes? Any noticeable performance improvement since they have been installed? You feel any loss in low end torque? Any sound difference? How was the fitment? Plug and Play?

    Engine is still out for service so fitting them shouldn't be difficult as everything is out of the car. Will let you know the rest when it is all back together.

    Thanks Brother! Also wonder if installing these down pipes would cause any loss in low end torque?

    Hey man, Just put the 2nd head back together and the engine is still out with the headers off for ceramic coating. its been off the road for a year so I'm not sure I would be the best to tell if it has hindered the low end torque or not.
