As i was removing the old exhaust to install a new flowmaster cat-back, I noticed that the honeycomb filter in the cat was in pieces, there were even pieces in the intermediate exhaust pipe i removed. So i'm guessing i'm gonn have to change the cat the only problem is that i know if it stock or not. I heard that the stock cats were welded at the inlet but this one has a clamp on it and doesnt look like its welded. Also, should i be buying a 3" inlet for the new cat. What do you guys recommend?
PS, i've only had this car for a month and i dont know anything about its past repair jobs but i did notice it said "Midas" on the muffler i just took out so I cant say the exhaust is original.
i just looked through my Haynes and i guess the cat i got on is original because its just bolts on both sides i gotta remove. So in buying a new cat, I should get 3" inlet and outlet right?
Just take the cat off unless you have smog testing. If you want to keep it really mellow, i would suggest a catco or magnaflow cat. It was only like 50 bucks for a universal and 12 bucks for a guy to weld it on.
another option is to take that cat off and break the insides of it using a screwdriver or some hard metal bar and break it in pieces until its all out then no need to buy anything.
