I have a 2016 Mustang GT Premium. I have added Borla S-Type Cat Back Exhaust and a cold air intake. I'm taking it up a notch and adding headers and a Ford Performance Suspension. I like the Kook's headers (they're made in the USA), but wondered what you folks think are the best out there. Thanks.

 

My stainless works 1 7/8ths work fine and provided nice gains without the premium price. Beefcakeracing has some very good prices right now.

 

I have Kook's on both cars.
If you're concerned about inspection, they sell a " green " cat that's 49 state legal.
ARH also makes a good product.
Lots of holiday sales right now, good time to buy !!

No concerns about inspections. I'm just curious why my hot rod shop prefers American Racing to Kook's. He said the color on the headers lasts longer. But, this isn't a daily driver. I plan to take it to a few meets, but that's it.

 

My tuner sells Kook's & Dynatech, they suggested Kook's. ( N.J. is an inspection state )
I think Ford uses ARH on the Cobra Jets.
As far as color, SS gets a copper like color to it after several heat cycles.
