M256 3.0L Turbo Inline-6 Catless Downpipes

Unlock additional performance from your Mercedes M256 3.0L turbocharged inline-six with these premium heat shielded catless downpipes. Designed specifically for the E53, CLS53, GT53, GLE53, and GLS53 AMG-line models, they reduce exhaust restriction for faster turbo spool, sharper throttle response, and a richer AMG exhaust note.
