Universal Cat Sizing/Where to buy?

[Ghettokracker71]

I have a 1991 Fastback,and I have a universal muffler,and a header,...I want to get a high-flow cat for it and put all the exhaust stuff on at the same time(and my new CAI too:)) But I can't really get under my car to measure the stock one....I'd really like to get a universal b/c its ALOT cheaper....

Also,...where to get a good price on one?

Thanks in advance for any info...

(my flame suit is handy...just in case )

EDIT:I just finished searching,too...unless I am blind,I didn't see any anwers... :eek3d:

My question to you is, what is the point? You aren't going to be freeing up much if any HP.
