Norcal Dynamics Downpipes S58 2020 – 2023 BMW M3 & M4 G80, G82, G83

Note: Track use only includes lifetime warranty

Upgrade from the stock S58 downpipes to the Norcal Dynamics S58 catless downpipes for maximum airflow, power, and sound!

Our BMW S58 downpipes eliminate the back pressure caused by your stock catalytic converters. By upgrading to our downpipes, your turbos can now spool faster and achieve maximum power. Plus, your car will sound significantly better as well.

Expect up to a 30HP increase on a tuned BMW S58 with stock turbos, even more on cars with upgraded turbos.

The flex pipe section helps reduce the stress and unwanted vibrations from the downpipes.

• Compatible with right-hand drive and left-hand drive vehicles
