Mercedes Benz AMG E63 / E63s Race Downpipes

RK-Tunes Catless E63/s downpipes eliminate the heavy and restrictive catalytic converters in the factory exhaust system. By eliminating the catalytic converters, your turbos can breathe more efficiently which reduces back-pressure. This reduction in back-pressure creates a faster and more audible turbo spool, a deeper and aggressive exhaust note, and most importantly, an Instant 30WHP+ WTQ gain.
