Kooks or Stainless Works Headers for My Corsa Extreme?

[Paletero]

I’m looking at 2" headers with green cats to pair with my Corsa Extreme cat back. For those who’ve run them, which do you prefer, Kooks or Stainless Works?

How do they compare in terms of sound and power delivery?

If you have any experience or videos of either setup, I’d really appreciate any input.

I would go with Kooks or ARH, both are top notch. I've heard too many bad things about Stainless Works products on multiple platforms. ARH doesn't show any headers on their website for the CT5-V BW, but they do have them. My car is currently at Vengeance Racing being modified and ARH was one of the options they gave me. I chose not to install headers right now.

As for sound, they are going to sound the same and produce the same amount of power which is typically around 30whp.

i have stainless works headers installed - i like them a lot. headers come with cats but i am running mine deleted. sound clip attached - this is into the stock catback. i’m installing the rest of the stainless works catback soon - waiting for a break in the weather to trek to the shop.

I recently had Kook's headers and green cats. For the possible loss of a couple of horsepower it's not worth the possibility of not passing visual state inspection. The Kook's cats have mid-pipes that join just before mufflers. Pictured is the OEM removed exhaust and the installed Kook's system. Can't give you a power increase for just headers as I had other mods done prior and tuned after all done. With valves open a significant increase in exhaust sound, closed barely above stock.
