Upon the release of the 440i, it became instantly recognizable that the exhaust note from the mighty 3.0 turbo had fallen below the levels of expectation from owners looking for the emotional release that comes with driving such a powerful vehicle.
***** COMPATIBLE WITH UNDER BRACE *****
BMW in their defence offered in some part to
recompense owners with the MPE (M Performance Exhaust).
However, we believe that the MPE (and whilst
offering a nice improvement over the stock rear silencer), fails to fully hit
the mark sonically.
With this in mind, we developed the BCS Centre Silencer Delete Pipe set.
The result of installing our pipe set completely
redefines the stock exhaust note, not only by increasing the overall sound
output but by redefining the character of the sound and in so doing proving
drama in the form of pops and burbles which have become the stuff of legend on
this platform, especially in the Sport and Sport+ modes.
Now considering normally that the removal of silencers and resonators may introduce Unwanted Sounds And Frequencies (AKA Drone) into the passenger compartment, we are pleased to confirm that we have detected none of these said 'USAF's, which means there is no downside to performing this modification.
If you are looking for an even greater sonic experience
we have designed the pipe set to be upgradeable to our full Powervalve boost
actuated variable tone system. If this is of interest, please navigate back to
our product listing for the 440i.
As mentioned earlier the MPE goes some way to improving
the stock exhaust note, however, for some owners who are left craving more
sound, the temptation is to remove the centre silencers as well...
Having tested this carefully, we have discovered
that this, unfortunately, introduces drone into the passenger compartment which
is thoroughly unpleasant and spoils the driving experience.
To this end, we developed the totally unique BCS DDE
(Dynamic Drone Eliminator), the product is defined as being dynamic as it
leaves the sound increase in place, shaving off a fraction of the db's whilst
eliminating completely all drone.
We, therefore, suggest that if you have purchased, or have an MPE installed on your M340i / 440i and you are looking for a greater depth of sound, you consider the DDE variant
of this product and navigate back to the appropriate page on our 440i product listing.
The product is completely MOT friendly and suitable for both road and track use.
The fitting time for this product is 1 hour.
Please note that in order to install the centre silencer delete pipe set, the original BMW exhaust system will require cutting just before the rear silencer on the dimple that BMW provides to mark the cutting position prior to installing an MPE.
