Transform the performance and sound of your inline-6 Mercedes with the Untd. Performance Catless Downpipe for the M256 3.0L turbocharged engine. Designed for AMG and 6-cylinder luxury models like the GT43, GT50, GT53, GLE53, S450, and S500, this downpipe eliminates factory restrictions to unleash raw power, reduce turbo lag, and bring out a far more aggressive exhaust note. If you’re building a high-output street or track car, this is the upgrade that takes your M256 to the next level.
