Or the Subaru WRX STi, I think I like that sound better, just a throaty deep choppy roar thats hard to believe came from a 4cyl. But then most turbo 4cyl cars sound much better, the turbo wastegate I'm assuming is what changes the sound so much.
Mind you, they behave nothing like other 4 cylinders its only fitting that they sound better too.
Turbo cars sound great because they can have an almost totally open exhaust system, so at idle or low throttle they have a nice deep sound. But when they step on it, the turbo spins up chopping the exhaust pulses up so the car isn't obnoxiously loud. One of the guys in my motorsports club as a TDI that has been worked up to 180whp, the way it drives and sounds reminds me of 500cc 2 stroke motocross bike. Lots of torque and bark just off idle, but the motocross bike smokes less...
Another guy has a super charged Elise with a carbon fiber exhaust can just like a sport bike would have, it literally sounds like its ripping air when he stands on it, mostly from the supercharger through the intake I suspect.
