[DeTomaso] 104 dB at 70 ft

To David Londry,
If you are trying to meet the DB limit set by the track you may have a
problem. A lot of it depends on where their microphones or meter is set up
and the DB level being given off by your car can be influenced by the
exhaust tips on your mufflers. If you install down turned tips you may be
able to deflect some of the sound away from the tracks sensors. If you have
the typical straight cut or diagonal cut I would be concerned that your car
may exceed the 104 DB limit (if that is the limit.) Borlas are known for
"Enhancing the sound" like resonators, so they may actually make the car
sound louder ( then some mufflers) If you must be below the tracks DB limit
you will really need to test your car on their set up. The position of
their sensors when you pass the point that they take the measurement as
well as other acoustic factors will effect the reading and testing your car
with another system in another location might come out at a completely
different level. If you are not going to be able to test your car until you
get to the track and it is a distance from your home you might prepare
yourself by having an extra set of mufflers that you know actually diminish
the sound level with you so you are not prevented from running if your car
exceeds their DB limit.
