Take a photo of it and nominate it for shed of the week on
Barry Boys. I believe such exhausts are called 'fart cannons'. Other features to ridicule include shopping lists stencilled on the paintwork and red painted drumz of powah.
One of the neighbours pulled a superb one.....
There is another neighbour , and a friend of theirs who has a "Chavriolet" sits outside the house revving away
Elderly neighbour waited until the whole group was there, then went across and offered to look at the timing for him
When the young lad asked why, it was explained that if the engine was so poorly maintained that it needed to be revved all the time as it was not idling then it needed to be looked at
After that every time he revved, someone would ask when he was going to get his timing sorted.
He soon gave up wit the revving as it was becoming a joke with his mates as well
