Turbo upgrade only on C63S

Hello guys.
Is there any experience for keeping the stock downpipe for turbo upgrade on 2017 C63S?
I want to keep the oem downpipe and performance exhaust, but need some more HP.
I currently have a tune and High Flow Air Filter Set.
Any experience, what turbo upgrade?

Don't just bolt on the new turbos - you will need a new tune to take advantage of the updated power curve, increased airflow, and a bunch of other things a tune does to match whatever mods you have. Those turbos work great on a street driven car. Several companies make their own similar flowing versions of the 900 at different price points. Get whatever suits your budget and goals.

If you go too big on the turbos, you will need a significant investment in other mods to either take advantage of the new turbos fully, or to keep from spitting a rod or crankshaft plus a piston or two out the bottom of the motor if the fueling is not there at higher outputs. Speed costs money, sometimes lots of it, but will cost a lot more if you decide to go big, but don't upgrade other things for reliability, or don't have the knowledge to assess problems as they crop up. Easy enough to grenade a motor with a bad tune, bad maintenance, or just bolting on too much and hoping it all sorta works until you get everything needed to reach whatever goals you may have.

Everything starts with what you want. Different ways to get there. Some are more expensive than others. Good luck whatever you decide.
