I only wonder if the exhaust in this video has a catted or catless downpipe. Because in my case, I'm keeping the stock downpipe and I wonder what impact that will have.

I hate emissions testing. If only I didn't have to deal with that crap, I would definitely go catted dp at a minimum. I had 200 cell cats with my 992 Porsche and it sounded SICK!

That's a head scratcher. Literally, just by statistics, that should be impossible. You must just have an unusual amount of R8 owners in your town?

The flat 6 set up and the V8 are completely different as you know ... Im running catless on the GTS and its raunchy and badass in a great way. DP's will definitely help with the M850i and I dont think you run secondary DPs like the M versions (I only pulled the secondarys so no CEL).

No matter what you will gain more sound and tonal adjustments with your Fi... I like IPE too but again not the same recording device, day, condition, car, etc. They all sound pretty damn good.

Edit- the IPE part of the video is their own post and that one had their dps not oem.
