I wouldn't want that on my car either but you can add or stack on as many diffuser discs as the bolt lengths can hold. The backpressure drops, torque rpm curve raises, and sound gets louder the more you add on.

Remove diffuser discs and the exhaust gets quieter with a little ffff ffff sound added into the exhaust pulses at idle and the torque rpm curve lowers.
So in that way the supertrap diffuser tips are a good design and the only quick and easily tunable sound exhausts ever made.

I have a CC products exhaust system with dual supertrap mufflers on a BMW R90S motorcycle and I've experimented with the amount of diffuser discs so I have some experiece with them

Take all the diffuser discs off and it's just a straight pipe off the turbo like a "zork"

BTW, where did the word "zork" for a straight curved pipe off the turbo come from?
I never heard that term anywhere before reading these forums.
