I don't believe there is a downpipe for the F30 335i yet. I know companies are working on them, shouldn't be long as the design should be very similar to E90 N55 engines.

However, on a vehicle equipped with a turbocharger, an after-market downpipe can offer a significant improvement in performance. Because a turbocharger is essentially a pump, it's important for the pipes entering and exiting the turbo to have unrestricted airflow. On many turbocharged vehicles, the exhaust pipes coming in and out of the turbo contain numerous bends. If these pipes are bent using a cheap, crush bending process (a common situation for many vehicles), they can restrict exhaust gas flow in and/or out of the turbo.

By reducing exhaust gas restrictions, the turbocharger can spool up more quickly. Faster spool-up times mean more power and/or better fuel economy. As a result, many after-market exhaust manufacturers offer over-sized exhaust downpipes with mandrel bends.
What I was told by my dealer is they don't like downpipes and wouldn't see why they wouldn't cover things on my cpo warranty, but my dinan inhouse guy said downpipes = big no, no, for coverage. So I'm passing on it.
