dont wake the neighbours doing the exhaust at this time and becareful if its raining ul ruin all tht hair doing time 
exhaust is 1 piece from down pipe back, and only back box had a hole, so bought a cheep mk2 punto powerflow back box off ebay, had to cut pipe to fit ithmallett said:Looks painful Dave, even though it's not. Clean it and plaster it. Why did you have to grind the back box off?
