fitted the new one today - pretty easy . I've never done one before and the only hold up was cutting old bolts off (make sure you get a fitting kit with a new one). Hadn't realised how noisy the car had got - much quieter now. Just got to get some scrap money in for the old one now. One thing of interest the new one has only 2 cats instead of 3. They've joined the rear 2 together but it all fitted easily
