ive changed my cat as was noisy now the car is spluttering and making a terrible noise . the garage thinks either the backbox or the centre box is blocked with the innards of the disintergrated cat. Ive ordered a replacement centre box bust just want to try fitting it without the weld on backbox just so i know if its that is the problem. I know it will be noisy but should it run ok just so i can whip it round the block ??? any thoughts ???

cheers

Just watch out for your cab filling up with exhaust fumes though.
