how to make car/exhaust louder for free?
what can i do to my car to make it louder for free using things at home if anything without having to go out and buy things.
my car is a VW Up! and the exhaust is stock and has only a centre box and then a straight pipe back. there is not back box and it is very quite. cannot tell the car is running most of the time! (this is stock btw)
what can i do to my car for free to release the inner beast?!
