R44 BMW M2/M3/M4 S58 Catless Downpipes NON-CEL (G80/G81/G82/G83/G87)

We are proud to introduce our new R44 S58 Catless Downpipes for 2021 G80/G82 M3 & M4.  Reduce backpressure by eliminating the restrictive catalytic converter in the factory downpipe which results in a faster spool, an increase in power and a more aggressive exhaust note. Handcrafted from stainless steel and CNC precision-machined flanges constructed from billet 304-grade stainless steel. 

The downpipe is supplied with a CAN MIL delete module to ensure no check engine light is shown from removing the factory catalytic convertor. The CAN BUS module is automatically DISABLED, if a BMW Tester is connected to the car. There will be NO error entry by using the LEIB CAN MIL DELETER.

If you will be doing software upgrades/tuning and wish to code the check engine light out yourself, please see our standard R44 S58 catless downpipes here.
