Last time I asked (at dealer) I could only have the whole package, ECU + complete sport exhaust system, if I wanted to tune the engine. I'm not fond of a loud exhaust, so decided not to do it. However, if the ECU flash is also available without it, I'm keen to hear (read) the results!
No change Thomas, you must still have the whole package. The silencer is full size and the noise is not much different to the standard GDI.
