RK Autowerks catless downpipes eliminate the primary exhaust restriction to improve flow, helping the turbos spool faster and reducing backpressure for immediate horsepower and torque gains. Designed using advanced 3D scanning and prototyping, they deliver OEM-like fitment and proper alignment on the vehicle.
Built from mandrel-bent T304 stainless steel with CNC velocity stack turbo flanges, these downpipes feature precision TIG-welded construction and heavy-duty V-band/exhaust flanges for a strong, leak-resistant connection. O2 sensor bungs are mounted in the factory locations for straightforward installation.

Flange Style (Important)
This version uses a 2-bolt flange connection. Confirm your factory downpipe style before ordering. BMW changed some 2022+ vehicles between slip-fit and flange-style setups, and selecting the wrong version may not be eligible for returns/exchanges.
WARNING (Emissions / Legal)
Catless downpipes are for off-road use only. Installation will typically trigger a Check Engine Light / Service Engine Soon warning. Removal or modification of emissions equipment is prohibited for vehicles operated on public roads in many jurisdictions.
