MODE Design RHD Downpipe B48 2016+

Improve exhaust flow, turbo response, and sound with the MODE Design B48 Catless Downpipe.

Designed as a direct replacement for the restrictive factory catalytic downpipe, the catless design reduces exhaust backpressure and allows the B48 turbocharger to operate more efficiently. When paired with an appropriate ECU calibration, it can support improved throttle response, stronger power delivery, and increased performance potential.

Manufactured from high-quality stainless steel, the downpipe features precision-machined flanges and durable welded construction for reliable fitment and long-term performance. It also delivers a deeper, more aggressive exhaust note without requiring permanent modifications to the vehicle.
