V8 or not

I went away for a week and when I came back my car was a V8.  It looks like a Nissan Pulsar Vecta but it sounds like a V8.  At first I thought that I had forgotten just what type of noise my motor produced, however, it is not my imagination; the car has transformed into a formula one racing car.  Now I know that the mechanic will tell me it is the muffler.  I know that, but I kind of like my little car scaring all the other little cars on the road.  I love that I can put my foot down and the engine growls and burbles when I rev it.  My plan is to wait for a police person to tell me that my car has a noisy muffler and I will obediently go straight to the mechanic.  However, until the day I think I will tool around in my sexy sounding car.  I may look like a little old silver haired lady but I am driving a souped up Nissan, just listen you can hear it for yourself.
