Get closer to GTS engine sound with simple mod

[Bucketsbentley]

This should be a fairly easy mod to increase engine noise in cabin towards GTS spec.

For the GTS, BMW did away with 2 sound insulation parts between the engine & cabin. No other stripping of insulation was made at the front of the car for the GTS.

The parts in question are 2 identical items for the left and right side labeled "3" in the diagram.

This, with a couple of other minor mods (like water injection, engine tune for start-up roar/burbles, carbon fiber hood, and titanium exhaust) should get you pretty close to the GTS sound Also, active sound delete.

Now, if you wanted performance in addition to sound, that might require some more serious mods...

Not all of us have mega bucks to spend on mods
