Catless setup. Review local emissions requirements and product notes before street use.
Designed to retain OEM-style fitment without cutting or welding on supported applications.
Downpipes can affect emissions readiness, sound level, and calibration needs. Review the product description before ordering.
Upgrade to the CenCal BMW N20 catless downpipe to eliminate the backpressure caused by your stock catalytic converters. By upgrading to our downpipe, your turbo can now spool faster and achieve maximum power. As a bonus, your car will sound a lot nicer as well.
Expect up to a 30HP increase on a tuned BMW N20 with stock turbo, even more on cars with upgraded turbo.
The flex pipe section will help reduce the stress and unwanted vibration caused by heat and engine movement.
Fits N20 engines only, please check your car and confirm that it has the N20 engine before placing an order.
