*background* I took the car in to be serviced at the dealership about 5 or 6 months ago per the "recall" letter stating that if the car is throwing a code for a malfunctioning cat, they will replace it... whatever. they said they replaced it and the light went away. shortly after i noticed this strange tick. Much like the sewing machine noise people get with a bent pushrod. Someone mentioned that it might be an exhaust leak however. I snooped around and found it was coming only from the right side of the car, up front where the cat is. i put 2 and 2 together and figured they didnt install it right. Took it back and they said it was my loudmouth exhaust leaking. I ******* hate dealerships because it is clearly the cat. not wanting to take it up the butt from them anymore, i left and here i am
anyone have any advice on taking out the cat and reinstalling it. will i have to break off any bolts. should i get a new one? should i take off the y pipe first, then the cat or what. i dont know where to start

any help would be great.
