Anyone knows if S550 GT cat backs with active valve exhaust fit on S650 (convertible)?

Most do, check lethal performance I believe their website is updated for what fits

I can say from personal experience that axle back exhausts will interchange.

Active S550 kits will not work on an active S650. This is due to the change in orientation of the active valve motors on the S650s. They're clocked differently than they were on the 18-23 cars. So even though the system may bolt up the valves will not work properly.

You'll want an active kit made specifically for the S650. Feel free to give us a shout. We have a bunch of systems on sale and always offer discounts to our M7G fam.

Thanks!

Thanks a lot for the detailed information

I live in Germany and need mufflers with a specific approval number to be legal so will have to wait until manufacturers will apply for and get them. Sooner or later they will start the process.
