insane exhaust sound from RPI

[eggman51]

My youngest daughter edited this selfie vid. Captures the RPI sound in a tunnel. It's NUTS. I love it. And hate it hehe.

I got black flagged at the track for noise limits, so need to tone it down a bit. Not convinced I will keep these, but I LOVE the sound at the track, so I am going to see what I can do to slightly lower the volume and make modifications to eliminate some of the drone.

Exhaust is:
SuperSprint v1 Stepped Headers
SuperSprint Oversized Catless Section 1
SuperSprint X-Pipe
RPI "Mufflers"
Fancy Wide diffuser (I mention this because I think it is amplifying the exhaust volume)

Eggman!
THIS.IS.NUTS.

Such a sound emitting from your Z4MR!

SO great to see your ride back on the road.

Are you on the other side of the repairs and all is good?

Nice -- but can you get her to edit out the music? Maybe I'm showing my age but I really just wanted to hear the car.

Can you hear the CSL intake with the RPi?

Inside the car, no.
From behind the car, no.
From in front of the car as it is approaching you at wide-open throttle, yes.
Under any other circumstances, no, you only heart the exhaust.

At least for my setup which was oversized headers, oversized catless section 1, straight pipes xpipe, RPIs.

What sparco seats do you have fitted and how easy were they to fit/ mount ?

I used the Sparco QRT seat because they are known for being roomy, without being wide.

I used the Brey Krause seat mounts and I preserved the electric slider.

I am not that handy with cars and such and this took me a few hours, was not difficult at all, the most time consuming part being the electrics for the seat slider.
