Hi-Flow Cat's HELP ME OUT

Hey guys. I just installed my Greddy sp2 exhaust(2004 model just came out) on my 1990 integra. It sounds AMAZING, but I need a new catylitic converter. Im thinking of getting a hi-flow cat. What are the best brands of cats? Are the cheap ones on ebay any good or are they shit? If someone knows where I can get a good hi flow cat for cheap....HELP.

if you need to pass emissions (like in Cali) get a real cat. Otherwise (a cheap solution) you can gut your old cat. I have an ebay one, but i dont use it. the "test pipe" are just a hollow piece of metal that lets exhaust pass straight through it, so i dunno how much better an expensive one can be vs. an ebay one.

I would go with a carsound cat, random tech cat or test pipe. If you gut your cat it will make the car slower, the gutted cat will act like a chamber that is larger than the exhaust pipe and cause the exhaust gases to change directions and cut down on flow.

But we have emissions in NY state.

Every state as emmissions....but they differ...
I dont think NY emmissions are like Cali....

i would go buy the test pipe, put it in, enjoy the extra power, then put in the stock cat...and exhaust when you get your car smoged.
