OK dont shout at me for asking a silly question.
I have a 3" exhaust with a 4.5" tail pipe.I have just put a bung in,that has now reduced it down to about 1.5".Have now made the rest of the exhaust useless as the air is fairly free flowing until it reaches the bung.
So by this thinking would I be better off just getting a standard exhaust.
A few people i have spoken to seem to keep their bungs in most of the time.
Just to add the bung has only really been added to reduce the noise.Neighbours not to happy when i leave at 6:30
