Mercedes-AMG CLA45 C118 Spool Race Downpipe

The Spool race downpipe for the Mercedes-AMG CLA45 (C118) replaces the restrictive factory downpipe to cut backpressure and sharpen turbo response.

Why you need it

The factory downpipe holds the turbo back. This T304 stainless downpipe uses smooth mandrel bends and TIG welds to move exhaust out faster, which brings quicker spool, better throttle response and a louder AMG note. With a proper tune it supports more power and torque.
