Speccing up a V4S at the moment - I'm trying to find out info about the differences between the Akro exhaust which is part of the V4S Full spec package, and the full racing Akro exhaust (a dealer option) - obviously the racing system consists of more bits and I know there is an engine map for it too - but does anyone know if the silencers themselves are the same / different / sound different etc..? Obviously I'm trying to figure out whether it's worth the upgrade to the full system - I'm not sure that a little extra power would be a big factor. seeing as the 170BHP is already pretty mental! But the sound might be a factor certainly, and any other effect on the motor's performance / smoothness etc..
The end can is different, as it has two inputs, not one. For the smoother power delivery, torque and sound, it’s a great upgrade.
