Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hi there,The fundamental difference that works against your replication of the Audis exhaust note is the fact that the Audi is a V8, where the Maserati is a V6. V8's are renowned for producing a distinct note due to the ignition timing in concert with exhaust tuning.
You could look at the possibility of modifying the wastegate dump & exhaust tuning on the Maserati to create something different to stock, but I would be careful modifying anything if the vehicle is still under warranty.First stop may be an aftermarket turbocharging specialist. They are frequently called on to do precisely what you are asking, but pretty obviously not anything from the Maserati line very often.I don't know of any business in new Zealand that specialises in Modifying late Maseratis, so there may be some trial & error involved. It would be nearly impossible to 'hurt' an engine via playing with the exhaust after the wastegate or dump valve, so that may be a possible course of action..Best of luck & happy motoring!Scott
