I have a 2006 4/4 70 th Anniversary édition with a 1800 Ford engine that was imported into Switzerland in 2007 with a Certifcate of Confirmity stating that the noise level at 4750 revs should be 88dB, after changing the silencer to part MEX1107 I still have a reading of 95.8dB . How do I reduce the dB ? I have been told by various sources to :
- try silencer MEX0175
- try silencer MEX1370
- use a dB killer
- have a silencer specially made
- add an additional silencer after the rear wheels….but which one fits/ works ?
- Librands acoustic trim in tail pipe ? Does it give sufficient reduction in dB ?
I need to find a solution before Oct 2 nd when the car will be retested. Feeling quite desperate! Thanks for any input
