One manufacturer, Lummen, Belgium-based Bosal claims that it now has the technology - borrowed straight from that used in naval submarine detection - to model the sound exhaust systems would make based on any particular car.
In other words, an exhaust noise can be carefully developed to match and enhance the characteristics of the car and to boost its street appeal.
This facility could deliver an important boost to the aftermarket - with an entirely new selling proposition for exhaust systems.
“You want an exhaust which delivers a throaty roar discernible in the car interior, sir?”
Dr Piet Steenackers, Bosal International technical director is evangelical about the technology. “We can now model and assess the sound signature of an exhaust system very accurately. In other words, Bosal can predict what the exhaust system fitted to a particular engine/car combination will sound like, both inside and outside the car, even before the first prototype car is built.”
While the technology has been previously restricted to its work with carmakers for OEM-fitted exhausts, it is now applying the technology to its aftermarket exhaust products.
“Bosal's aftermarket customers now get products which are not only excellent value for money but will also be music to their ears,” says Steenackers.
