RK Autowerks catless downpipes remove the primary exhaust restriction to increase flow, helping the turbos spool faster and reducing backpressure for significant horsepower and torque gains you can feel immediately. Designed using advanced 3D scanning and prototyping, these downpipes are engineered for OEM-like fitment and proper alignment.
Manufactured from mandrel-bent T304 stainless steel and finished with CNC velocity stack turbo flanges, each downpipe features precision TIG-welded construction and heavy-duty V-band / exhaust flanges for a secure, leak-resistant connection built to last. Stainless O2 sensor bungs are mounted in the factory locations for straightforward installation.
