Free up your exhaust with our Catless downpipes!
RK TUNES catless 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, a 10-30WHP increase depending on vehicle modifications. In order to prevent a Check Engine Light, an ECU retune or 02 sensor spacer is recommended.
