What's the difference between green catted and catted connection? One just more environmentally friendly? More power with the green catted because it sure cost alot more. Thanks

Just searching the forum for an answer to this.

All I could find was in this thread...http://www.mustang6g.com/forums/showthread.php?t=17629&highlight=kooks+headers+green+catted

I think the green catted is probably more restrictive (i.e. produces less hp) because it is more emission friendly (I'm in Cali. so nothing is emissions friendly)...but don't quote me on this since its only my opinion so I could be wrong.

I'm guessing the green catted is more expensive because the cats included on them probably have a denser filter element like the OEM cats. But again this is only a guess, so I could be wrong.

My main reason for considering to buy the green catted Kooks LTHs is to reduce the sound. I already have a Borla S-Type catback and it is loud enough as this is my DD. I'd really like more power from an intake/LTH/tune combo, but I really want to minimize any increase in sound from the LTHs.

I'll definately call the vendor where I'll purchase the Kooks green catted from and ask about the difference...I encourage you to do the same before purchasing.

Anyone else with more info., please enlighten us!!!

I think I'm gonna go with ARH long system from hypermotive and keep my stock mufflers. I should still make as much power with the stock mufflers as a aftermarket muffler. I can always get axle backs later

This is what I just did. ARH long with h-pipe. Plan to use factory mufflers for now. Though I got mine Beefcake.

Beefcake,

Can you give us a break down on the Kooks green catted versus high flow catted?

As in which makes more/less power and which is louder/quieter?

I'm on the cusp of ordering these

Thanks!

I have the Kooks long tube headers with the high flow cats. I debated between the high flow cats and green cats but didn't want to spend the extra $500 bucks. When the headers were installed, it only took a day for the check engine light to come on throwing the emission codes. I asked several vendor if they only sold the green cats, and they all said no so I contacted Kooks directly. Needless to say, they wanted $1100 dollars just for the green cats. I asked what the difference was. The green cats will not cause a check engine light. They supposedly flow the same as the high flow cat. I just had my tuner fix the check engine light. Love the Kooks headers........

Thanks for the info. Makes sense to go with the high flow, non-green cats and just have the CEL tuned off. That 500 bones could go toward the tune.

Couple questions...

Are you running an x- or h-pipe or catback? If so which one?

Also, did you notice a significant increase sound after the LTHs install?

I am running MBRP race exhaust with an H pipe. Did not notice an increase in sound after headers, it actually reduced the drone a little thou.

Good to know. Thanks again for the input.

I'm gonna go Kooks, high flow cats then! :cheers:

the green has a 49 state epa stamp on it. they also burn hotter, so you can keep the rear 02s enabled if you choose too

lastly, where typically they recommend high flows to around 10psi or 700 hp cars, the green cats are good for closer to 900hp

This is exactly the reason I justified the extra cost. They truly are a phenomenal cat and it will be nice to not worry about MA emissions.
