My exhaust is doing my head in. I got a new standard back box put on about 3 months ago and its been rattling ever since, the rubber bits at the back have been replaced for tighter ones but its still doing it.
Its ok at standstill and with me in, but the more people that get in, the worse it is, especially over speed bumps or pot holes.

Any ideas will be much appreciated.

sounds like it cud be hitting the rear axel.

How would i stop this? :/

mines been lowered 40mm and rattles but it did this even before i lowered it. with mine it does not bang on the rear axle but the actuall backbox hits the spare tyre well.

its because its a triangle shape backbox,the top point of the ''triangle'' hits the floor of the car.

ive just left mine,even tho it does my head in too,but i suppose you could try longer rubbers so it sits a lil lower or maybe try and twist the backbox so that the top point of the ''triangle'' sits slightly to the left or right.

only other thing to do is try and move the backbox further back on the car.

or maybe cut one side of your rubbers so that the backbox drops a lil bit under its own weight,but dont cut both sides of each rubber or youl be buying a new backbox and rubbers coz this one fell off!
