Recordding exhaust notes is somewhat of an art.
In a previous life I worked as a programmer and part time music studio engineer for a company making computer games. We were making a racing game, and required 'rally' car engine noise.
I found that capturing this sound on a rolling road, required the mic to be muffled, and in the car footwell for the best sound and no distortion.
Having said that a good microphone is a serious assett in these situations as it will handle dynamics far better than a built in camera mic.
IDeally I could bring a recorder to a meet (when we manage to arrange one we can all get to!) and then we can get side by side comparisons to post on here so others can get an idea before they take the plunge..
