Hi all. I’ve had my G87 for over a year and it gets better and better.

I have turned M noise off and wondered if this slightly reduces power or if it’s just a noise when a valve opens.

Cheers and look forward to your thoughts

Agree these cars just get better and better!

If the valves closed reduce power it is negligible to the point of nearly zero. The cats are the bottleneck.

Thank you for your reply. Good to know as I’m not a fan of the M noise but the engine itself is spot on
