I forgot to add a photo of the underside, it's really quite a rigid construction.

-How is the noise at highway speeds at steady low rpms, when going like 120 km/h? Is it like a stock one where it’s mostly just tire and wind noise or is it more noticeable?
Now, how about a clip showcasing the sound under full-on acceleration
Edit: Just listened the clip with a better speaker able to handle lower frequencies, now I really wan’t do mine.

I can't really tell you much about the before and after situation, I'm afraid. When I'm on the highway at about 100-130 there is no exhaust noise at all. You only hear it when accelerating.
Thanks Timmy! 😄
