For M3, our system removes the secondary catalyst and resonator to ensure the high flow of the exhaust gas and the exhaust tone.
Also our muffler section is carefully design to maintain optimal gas pressure to create good power all around the RPM range.
We always aim for the best sound, then performance comes in second which does NOT mean our system loss power over highly restrictive stock exhaust.


But we do admit that on some applications, there was slight power loss during silent mode due to configuration of the muffler system.
Our silent mode valve is adjustable to compensate this issue.
So it depends on how the owner set up the system.
You can make our silent mode quieter than stock car on some of the application.

Thank you for the info.
