This. It’s the single most important mod and makes the RS sound and behave like it should have when it left the factory.

I have one on my 2016 PFL and it’s easily the best mod i’ve done.
The sound is unreal.

so what does it actually do, so you can control the pops etc.

Is it $550? Looks like something Delboy would sell that Bob made in a shed for 50p, lol

It controls the flaps in the exhaust and changes their behaviour. Also functions as a stop/start memory.
