Default Headers

So I had kooks 2 inch headers and green cats put on my 2016 Z06, 7 speed. Car was tuned, also Corsa Carbon Fiber Intake was added, DSX lid and 95 mm solar performance throttle body. Dyno sheet says 596 at the wheels.

It does not feel like 596 at the wheels. The Z06 felt much faster prior to upgrades. Anybody have any similar issues? I think I’m going to go back to the stock set up for the exhaust.

If its slower after the headers, I would suspect there is an issue with the tune. Primarily the throttle may be closing. If you tuner doesn't know the Gen V stuff then you could very well have gotten a bad tune. I see this often unfortunately.

Thanks for the info. Before the work, I would have some spin even passing in 3 rd gear and I could really feel the car pulling. Now it’s just a lot of exhaust noise, very flat.
