Our catless downpipes are made from T304 stainless steel and are 3" in diameter stepping down to 2.5" to join the front pipes gaining up to 37.5 WHP and 51 WTQ. They remove the primary cats allowing the turbo's to spool up faster providing greater throttle response whilst lowering EGTs (Exhaust Gas Temperatures).
Combined even with the stock exhaust the performance as well as the sound is transformed without any drone. An ECU Remap or a Delete-R Module are required to prevent the CEL. You can also combine with an Awron Gauge with Valve Control to give you control over the volume to suit your mood.
