The downpipe is perfect for production and upgraded vehicles.
By installing this downpipe a slight increase in performance as well as an improvement of the response behavior can be seen.
Another deciding factor for the purchase of this downpipe is that the exhaust gas temperatures drop and the turbocharger is relieved.
