Hi Michael.
I hope you are well.

Thank you for the 5 star review and kind words we really do appreciate this.

I know what you mean the induction noise from the M135i is insane you should try going through a tunnel it echoes haha.

Install as you said is a breeze due to being a bolt on upgrade and being designed here in the UK on our own cars! So we know them in and out.

We do hope you choose us again in the near future maybe for an exhaust ;)

Kind Regards
Sam
