Mine is 2023 RSQ8 without optional sport exhaust since Aakrapovic exhaust is my plan, installed Aakrapovic few weeks ago and a little bit disappointed as the sound was still quiet but just differnet tone compared to stock exhaust. Installed RedStar HJS HD 200cpsi 143mm Downpipe with straight midpipes last week, super satisfied now. See video:

What tune are you using and are you getting the CEL and if so did you try post cat O2 sensor extensions (45 deg, 90 deg, etc)?

I'm running stage3 software from PowerDivision Poland.

I did not try stock tune with RedStar DP to see if getting CEL, but I read somewhere on the internet that people running DP with HJS cats does not get CEL.

Default Anyone have a pic of the stock RSQ8 exhaust from underneath the car?

Hi Everyone. Does anyone have a pic of the stock RSQ8 exhaust from underneath the car? I am trying to figure out what to do for my exhaust and seeing the stock exhaust visually will help me decide. I think I am leaning towards the RedStar H pipe, anyone have any thoughts?
