GRP Engineering Turbo Back Complete Exhaust System suits Toyota GR Yaris 4.5" into 3" to Twin 2.5" Stainless Steel


GRP Engineering 4.5" stainless steel dump pipe including 3" mid pipe and 3" into twin 2.5" cat back system.

This stainless steel Turbo back exhaust uses a massive 4.5" expansion pipe directly from the turbocharger into an extreme high flow 5" cat removing both of the restrictive factory catalytic convertors. From there it then merges into a 3" mid pipe with a high performance bellow flex join and connected to the GRP 3" into twin 2.5" cat back system. Increased performance, deaper and louder exhaust note and more turbo noise can be expected with this bolt on upgrade, no tuning required and no Cel/Engine lights on the test vehicle. (A very small number of customers have experienced random Cel lights after extended driving periods, these have been easily cleared within seconds via $30 obd2 scan tools or obd2 bluetooth phone apps, and no noticable effects to performance with the dash ligh on).

Would Suit :
