Why do you want them?

Are you trying to create your own active exhaust?

just getting my feeler out there. NC emission test is a bunch of bull. Hopefully the end emission testing bill they just made will pass soon.

I installed some from Kooks so I could pass emissions. On my 2017 GT with the GT350 intake manifold, 47# Ford Performance injectors, Steeda intake, Kooks 1-7/8 primaries long tube headers, Corsa Xpipe Catback, PBD 91 tune, after install I notice the exhaust was a tiny bit quieter and that was it. No change I could feel in the seat of the pants and air/fuel ratios were the same.

Nice I have a set off stainless power ready to go on. Do u think the kooks cat will work on this application

If you want true high flow, you have to get G-Sport ones but they're not cheap. The ones you posted are most likely garbage.

GESi G-Sport or HJS are your only real options. PLM is rebadged junk, anything they sell is rebadged junk.

Or import something EU compliant.

No, just had them installed to pass emissions, didn't care about hp numbers. Holding them in my hand I didn't see how they would cause much, if any, restriction. Don't even know how they could call them a CAT but in AZ they just needed to see a CAT there when they stuck a mirror under the car. No DOT stamps or anything on the them. These are the ones https://www.googleadservices.com/pa...9OL6sz-AhVUIH0KHal-CocQ9aACKAB6BAgHEBA&adurl=
