Hey,
I’ve had the cat changed due to old one rattling. Picked up car today and don’t know if it’s placebo but seems to boost abit better, however it almost seems like it squeals abit now which increases under acceleration.
Anyone any ideas? I don’t like taking the car back if alls okay but on the same point I don’t want to get to an MOT in 9 months and find out I’ve got exhaust blowing or something.
