I am thinking about getting a high flow cat for my 1990 olds eighty eight and could not find what i wanted on the search. I am wondering if i can do this myself without a welder.
Here are some pictures of the cat as of now.

It looks as if you could just pull it off and put a new one on.
What brand and type and or part # would i get. A link to and exact fit would be great.
What would be involved in doing this if i did it myself?

Anyone?

anythings possible, u could cut the old cat off, and put a high flow on with exhaust pipe clamps, thats how my jeep was from the factory.

I was hoping it would slide out so i wouldn't have to cut it. Maybe if it does slide out then i could loosen the exhast up and take the old one out, put a new one in and seal it with a exhast sealer. Does it even look welded? I cant see any marks.

Does it sound any better?

That'* exactly how the Magnaflow cat was installed on the Olds 88 Royale I had. The muffler shop did the work. I wish the would have welded a bead on it instead, but it worked nonetheless.

If you see no clamps, it was weleded. Probably at the factory and it'* a super clean job.

In either case you'll pretty much need to cut the old one out, put the new one and some pipe in (new ones are usually much smaller)

Thanks man, ive been waiting for days on an answer on this.
