Theres no leaks in it, the garage had it off and refitted it, and then we took it off and refitted it.. still does it, guess theres summet up with the insides of the exhaust itself then, he got 12 months guarantee with it, told him to take it back and ask them to fit another exhaust but hes not the most ballsy type of lads ! It does it more when its hot than cold..

thanks
