Willow Performance are excited to introduce our 3" Catless Downpipe for BMW S55 Engines. This Includes the following models: 

F80 M3 & F82/3 M4

 

Our catless downpipe has been fitted to our M4 CS demo car and has not only vastly improved turbo spool, throttle responce, sound but is also allowing the turbo to perform in cooler condition with less back pressure prolonging life. 

 

Expect gains of around 20hp from this one modification. This has been proven by multiple dyno's. This is truly a must have for the S55 engines and really do wake them up. Main beauty with our downpipes is the fact that they can be fitted to either factory or aftermarket systems with no issues. 

 

Please be aware that it can take up to 2-4 weeks for delivery if the item is out of stock.
