I've had a strange noise from the back of the car for some while now. Seemed to start after having a Milltek cat back fitted. Sounds like rubbing or vibration against the underside and only happens' with engine braking at about 2000 rpm going down hill and when things have warmed up. It will stop if I disengage the clutch or press on the gas pedal. It is also more prevalent when I've got weight in the back. I've been underneath many times but can't see anything amiss. At one point I thought the exhaust was touching the ARB when it got hot...
Any idea's ....
