S55 F8X Catless Downpipes

Upgrade from the stock S55 downpipes to the S55 catless downpipes for maximum airflow, power, and sound!

Upgrade to the BMW S55 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 S55 with stock turbos, even more on cars with upgraded turbos.

Features:

• 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 turbo
• Spot on fitment

Fitment

• 2014+ BMW M3
• 2015+ BMW M4

(we stock many s55 downpipes including MAD, Cen-Cal, Agency Performance. 
All of these are produced in the same factory so product is identical)
