E92 LCI M4 FRONT BUMPER

Upgrade from the stock N54 Catless downpipes to the Cen-Cal N54 catless downpipes for maximum airflow, power, and sound!

Upgrade to the Cen-Cal BMW N54 downpipes to eliminate the backpressure caused by your stock catalytic converters. By upgrading to our downpipes, your turbos 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 N54 with stock turbos, even more on cars with upgraded turbos.

Compatible with right-hand drive and left-hand drive vehicles
Smooth bends for maximum airflow without any drone
Up to 30HP increase on the stock turbos, even more on upgraded turbos
