Ive got jba long tubes with the jba h pipe with cats, but people sometimes ask me if im running high flow cats on it.. im pretty sure im not but i honestly dont know, im guessing highflow cats is something aftermarket that you have to buy and maybe switch out with the cats that are on there now? how does it work if someone wouldnt mind telling me?

Yes, Hi Flows are replacements for your stock cats. They ar self explanatory, they allow a higher air flow rate than stock cats. This works by allowing the cart to breathe better. It's like drinking a soda with a coffee straw vs. drinking a soda with a regular straw. And with no cats, it's like drinking from a beer bong... [8D]

They are all probably about the same.

Carsound/magnaflows are very good.

+2 Personaly I went with the Magnaflow High Flows in a true X setup. Sounds great and added power.
