Hi all, I got my 182 just over a week ago now its an 04 plate in silver with 30k on the clock the car is in excellent condition but I do have one query the car sounds fine when im just poodling along but if I accelerate hard it sounds really raspy from what sounds from sort of right under the middle of the car, is this where the cat is located on the exhaust and could it be a knackered one? I would appreciate your views! Thanks.
