Hi guys, my mate has a 5 door corsa b lowered all the way down on coilovers and had an aftermarket exhaust however he has taken that off now and gone standard. but when he pulls off and drives normally so to speak it keep crunching the sound is awfull. not sure what it could be? it's not when it's going over a bump or anything just does it on normal driving use....

Had that on mine when reversing. One of the rubbers fell off is why it happened to me

Exhaust is prob hitting the back axle either twist the back box so it sits higher over ther axle, fit poly bushes to stop movement or fit a after market hanger
