WTB Porsche 991 turbo performance exhaust

it honestly depends on your goals. Generally, Catless will give you more power and sound but you'll have a CEL and potential emissions issues. HJS Sport Cats are what I recommend for most as you'll see majority of the power/sound of Catless but with no CELs, raw gas smell or emissions/inspection issues (in most states).
Feel free to give me a shout if you'd like to discuss options! 267-742-3047

I have a cat less Kline system if your interested. It’s not the standard choir version but 76/70mm medium + system which is louder and more capable of higher HP. Let me know if you want a video.
