Lancaster County PA didn't used to require emissions, so I took my AIR system and cat off, and ran 3" flowmaster pipes back from the headers. Now, they require emissions. Last year I got away with it because I drove less than 5k miles, so I got the exempt sticker... this year, no such luck.

So I would like to throw on a high flow cat, because I don't want to restrict my exaust... Like I said, I have 3" flowmaster exaust running back. Just wondering what everyone else is using for high-flow cats? I did a search, couldn't find much...

I think Meineke might let me get away without adding the air system... which would be awesome! lol.

If I have a stock 305 TBI with stock exhaust and stock cat. Would that catco cat fit in my stock location or not? I am asking this because I want to but a cat back system on my car, but I dont want to buy headers yet. I want a high flow cat that will fit right now to my stock system and will let me to expand to my headers and y pipe when i get the money.
