C7 S6 downpipe question

A6 All/ S6 All
#1

I did the Resonator delete and just had 2 straight pipes welded in on my 2013 S6. Sounds great, nice growl even at idle.

I haven’t gotten tuned yet, but my next thing I’d like to do is downpipes and get rid of those nasty golden snakes.

I am not looking for cheap, but $1,000 less makes me open my eyes to build quality and fitment.
I saw these Russian made cat-less downpipes on Ebay. you can get them uncoated or even ceramic coated.

I was then going to add these O2 extenders with built in mini-cats.

I don’t see the point in spending 2,000 for a 2.76" APR DP or more for a Milltek that doesn’t even bolt up to the factory Cat back without modification. when I can get one for half that much and the 2 Mini-cat 02 extenders should stop the CEL.

This downpipe says it bolts right up with no modification necessary, and the welds look rally nicely done.

What do you guys think?

Nobody.

Oh well. I’ll think about it and let you guys know what I end up doing?

I’m interested in if that mini-cat actually works.

There just aren’t many C7 owners on this forum. (shrug)

I thought about commenting, but haven’t done any research on aftermarket downpipes, mostly because I haven’t really seen any proof that they actually help…

I have been trying to look more into what you posted. The one down pipes you linked to looked like they would be fine. The 02 device. I dont know if that will actually work or not. You can actually just use a J bung and get the same results for a fraction of that price. I think there is a chance you would actually get a code for adding that as usual 02 devises allow flow to air past them. In theory the 02 device you linked to is flawed. There is a chance it could work but im not so sure
