Our cars have the AMG performance exhaust as standard; however don't know the case in other markets.Yeah, interested to see what you find. The cost /performance improvement of current tunes and mods has me scratching my head a bit.
Aus delivered cars don't have the particulate filter, are there other differences as well in the exhaust system?.
With the exhaust button on I find my A45s loud enough.
Noise level is no where near as important as back pressure.
I could care less what it sounds like, (so long as I don't get stopped!! ), so long as total system back pressure, as measured at the turbine outlet, is less than 0.5 PSI
i think it is probably true to say that our spec vehicles are as good as it gets for a standard, as delivered, A45S.
It will be months for me to obtain the data as outlined in my previous post, so please don't hold your breath.
In addition to the points listed, I am also going to need to monitor the fuel pressure at the tank mounted pump outlet and to the inlet port injectors, along with getting said injectors flowed.
At the end of the day, no point in bulk air, if there is problem with fuel volume delivery,
