High Flow Cats

[Helms]

I've had a Dynomax Super Turbo muffler sitting here for a while, and pretty soon I'm going to finally get around to having it installed with a custom cat-back. Is it worth getting a high flow catalytic converter to go with it or should I just leave the stock one on? If I do get one, do I need one with or without the little air tube I see on some? Thanks.

if you want to do the whole exhaust line, replace the stock cat with a high flow one, delete the resonator, and put your muffler on. you will be very happy.

You dont need the little air tube on our cars.

Are you talking about cats that work in conjunction with a smog pump? Our cars don't have smog pumps, so there's no little air tube to worry about.

I don't really know what I'm talking about. I'm just starting to learn about cars. Every cat manufacturer's webpage I've looked at just refers to the little thing coming out the side as an air tube.

Anyways, will the car not be brutally loud if I take out the resonator? I'd prefer to keep it pretty quiet. If I choose to keep a resonator in place, is there an aftermarket option that will dampen performance less than the stock one?

Thanks for the help.

is it just me or does that "AIR TUBE" look like one of the Hanger bracket thinga-majigs?

No, it's for use with a smog pump equipped vehicle. Cat's need O2 to function properly, and the old school of thought was to pump air into the cat so it would work. Now the manufacturer makes the mixture continuously switch between rich and lean to get enough O2 in the cat to let it function properly.
