The F10, like you said, is WAY more insulated from noise than the E60 (my RPI GTS got on my nerves at times I did not want to roar) but you definitely hear those exhausts (RARE-but there were definitely some times). Your sound is AMAZING but I think people who are concerned about the "luxury" side of things in terms of quiet will HATE it-no?-lol!
You are right about the shorter cold start. The F10 does seem to settle down much quicker. Honestly, my wife does not like the E-Race at all. It is too noisy to her (I thin she is jaded from the memories of that V10 with the RPI :-) I am switching mine out to a modified BMW exhaust and downpipes tomorrow. I am not doing this because of noise. I am doing it because the whole setup is perfectly performance matched with my tune. I like the throaty sound of the E-Race but for a time I did have the OEM mufflers with the valves wired open and it did give a nice sporty sound that I COULD hear in the cabin, just not at idle. The cold start actually sounded quite nice and refined. The new setup should be slightly louder but a big drop from the E-Race.
On that note...I have a NEW set of E-Race (not installed-this is a different set that I ordered and have not yet used. Returning current set to IND). It is the 90mm round with custom matte black powdercoated cans and gloss black powdercoated tips with a Silverstone M logo if anyone might be interested (not jackin your thread here-thought a few guys here are considering upgrades so I'd throw it out there. Hope you don;t mind.)
BTW-your car looks FREAKING AWESOME. I absolutely LOVE the blacked out touches you have done with the IND stuff (I assume itis IND). It is one of the best looking F10 M5s I have seen. It looks sleek and mean. I have the pics from your latest pic thread up on my other monitor and am about to show it to my wife. I think I want to move and I am going to show her just how pretty my M5 might look with some of those San Diego backdrops.

Coldlist, I'm curious to know what is being modded on the oem exhaust I was actually thinking about doing the same thing myself. You mentioned deleting the valves and going with bigger pipes. Are you guys also going to replace the packing and close the perforated tubes?
