    Current RS6 downpipe sources

    I'm sure this topic has been beaten to death over the years but all the threads I find are quite old and have links to vendors that no longer offer DPs.

    Does anyone know who still offers DP for the C5 RS6?

    Best I have found are these cheap ebay ones(unsure on fittment):
    https://www.ebay.com/itm/Audi-S4-4-2L-V8-RS6-4-2L-DOWNPIPES-WITH-CAT-Ko4-028-Ko4-029-Audi-Upgrade/123525995704?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.

    Contacted a few places that used to sell milltek DPs but no longer do. I'm sure they would be more than I would want to spend anyways.

    Thank for the help!

    This was the latest info posted only a few weeks ago, but not sure if you’re looking for stock or aftermarket...

    Looking for aftermarket.

    Would consider gutting stock cats as well but it seems like it would be a pain to gut all 4 cats.

    There is an outfit in Germany called "KWE" that I believe still makes them. Not sure if there is a US retailer, but I'm sure someone would ship them over here. I don't know much about the quality, but some folks over on rs246.com have talked positive about them.

    If you decide to gut the stockers, I would only gut the precat, I don't think there would be much or any benefit gutting the main cat since it's pretty huge and probably flows plenty well. I've also heard it messes with the exhaust sound quite a bit to create a big open chamber in the system.

    GreggPDX, thanks for the find. Here's a link to the site and the DP's, they have some other things too. Edit; doesn't' seem to offer shipping to the US, hmmmm, maybe ship to a friend in the UK, then have them ship over...
