Late again....
What will I gain ? Is it worth the expense ?
It was for me. If you get a buzz out of driving your car it’s worth it. It’s not about going faster, the lower end torque curve feels nicer and the car seems to be a little more willing. But I’m a cheapskate so did a DIY flash using a downloaded tune from Viezu.
Stupid question time...........
How do you know if your car is fitted with a sports exhaust or a standard exhaust?

On the factory silencer box there is a little welded plate with MEX1107 or MEX1105 stamped on. MEX1107 is the straight through noisy one.
