I'm wondering what the differences would be between putting in a hi flow cat, and no cat at all. Will there be that much more noise with no cat? Will a high flow still trip the check engine light?

Thanks

CELs are tricky - they seem to be vehicle dependant. My buddy can run with no cats whatsoever and doesn't get CELs, and some people get them when they look at their cars funny. I had a high flow cat on my Impreza, and it tripped the CEL after a long drive.

There will be a sound difference, but imho run with them. It cuts down on the raspy noises and helps to completely burn the fuel so there's less pollution. Pollution makes baby Jesus cry, so do what you can.

Magnaflow offers a High-flow cat that is really like 2 cats welded side by side. the unique feature of this cat is that it has 2 o2 sensors in it (one for each cat) which are piggy-backed into one plug for the factory hook up. this will give u the ability to run a high flow cat and also hook up a true-dual exhaust system on your dakota.
