Expert's advice:
The Evolution Racewerks S58 catless downpipes reduce the backpressure, which results in more power and significantly more torque, and reduces the thermal load on the turbocharger. Made out of high-quality stainless steel, the downpipes replace the OEM downpipes and fit perfectly.
Please note that the catless downpipes can cause problems due to the road regulations in your country. Remapping the ECU is mandatory after the installation of these downpipes, in order to prevent potential "check engine light" warning signals.
