Many people have criticised the brand new 2014 BMW M4 for
its weak exhaust note compared to the E92 M3.
Of course, it is hardly surprising that the stock M4 doesn't
sound quite as good as its predecessor .
Why?
This criticism seems to resulted from
its twin-turbocharged 3.0-litre inline-six.

Aftermarket exhaust manufacturer iPE is famed for
making awesome systems for your favourite performance cars,
and now Innotech's the M3/M4's turn.
Watch the iPE videos at the top ,then listen to your M4 with a stock exhaust.
Does iPE system enhance the sound, or do you prefer it standard?
