Noelle Motorsport catts here. Expensive price to gain 10-15 hp but the sound increase is noticeable.
There are a few other brands as well.

I have the Noelle's on order and no CEL with these, they are OEM parts from Boysen as I understand it. They are labelled BMW and just have higher flow cats in the front and either 400 in back or none. Spinny's have 400 in back, I am supposed to be getting a set with none in back and 300s in front. They are not cheap and I was told the hp gain would be 30hp but it appears not based on dyno numbers. |

Catted DP prices similar to Dinan exhaust with discount.
I don't personally care for additional power (to me, M5 power is plenty) but want to upgrade the sound dept. So I'm debating between catted DP+Cyba tips vs. exhaust upgrade (low budget as Dinan to full blown Akra). Anyone has video comparison of stock vs. catted dp?

Spinny got his in Europe directly from Noelle. I am getting mine from a guy in Alpharetta name of Ron Trochelman. His place is called Performing Imports. I think ColdList got his there too. Steve Dinan has them on his car so I am told.

I paid $4500, stealth looked into it and said I think $4700 installed so similar, and I think Spinny quoted 3200 Euro and he brought them back and paid the duties so somewhere north of $4000 depending. Not cheap but they are made by the company that is the OEM for BMW, there will be no CEL and the cats won't be lower tolerance or quality and burn up early nor will there be any issue with the oxygen sensor.

$3,200 with install included, the shop owner is a good friend of mine, plus i spent close to 30k on parts for the m5. i havnt gotten the chance to get it on the dyno, but you can def feel the car more responsive in a way that only a driver understands in his own car. i could easily say the ams catted dps are the best mod ive done to my car so far. akra + ams catted dps = glory. akra alone, not so much.

Deffo quicker and the turbo spool up is much more noticeable. Lovely cracks from the exhaust when up changing and backing off especially with the cp exhaust. No cel for me but I believe in the uk our emissions are not as severe as yours are in the states?
