Green cats are VERY high quality GESI cats. They will not melt. Power loss would be very minimal over open exhaust until you really start to push over 1000hp.

I am sure this would still be loud but not as loud as the Atak, right? Or would the difference be negligible due to no cats & headers?

So... Kooks LT 2" Headers, No cats, existing Borla Piping to AWE Touring Axle-Back? Is this ok to do or not recommended?

Regardless.... I am leaning towards No Cats/No Kooks Green Cats so not sure what would keep her as "quiet" as possible.

I have 2" Kooks, green cats, and the AWE resonated touring catback exhaust. Its still loud, but bearable. Its at the limit of what most people would consider acceptable. There's no drone though and under moderate throttle, it sounds quite good, full throttle though is loud.

I have the same setup except 2 inch csp longtubes, it’s definitely loud but I like it

Honestly I went with CSP 2" headers without cats into the factory suit case. If I put it in stealth mode it's actually no different than when I used to drive it in track mode when cruising. It's pretty quiet. But if you put it in track mode now it gets pretty rowdy. It's louder than it used to be, but still very neighbor friendly in stealth mode. I had never used stealth mode prior to putting the headers on, but now a cold start with the flaps open is quite the noise at 5am.

I have this exact set up

If you email me at Mark.Poole@ig.ca I can send some vids. They are too big to attach. Or add me on FB mark poole brandon manitoba and I can video call with you.

I have this set up and didn't like the sound very much and was looking for a stock suitcase but my builder talked me into some vibrant 12" resonators. The sound is better and at full throttle it is pretty amazing. Part "heavy" throttle is ok. It's something you can look into. My car still made 855whp and 790wtq with the resonators so they didn't add any restriction.

Mine has Kooks LT, hi-flow cats and Kooks AB with tiny mufflers. I could post a clip at idle, but such a system would not be great for a commuter or extended daily driver car. It drones between 1800-2200, which can be eliminated in a lower gear, but inside it sounds like an all-out drag car at WOT

By chance, do you have any sound clips of your set up? I have the same exhaust, minus the headers and grrrn cats. I’m still in the fence about getting Them because I don’t want the car to be insanely loud and annoying. Thanks
