Here's my idea to modify the OEM M2 Exhaust to M2 MPE. The goal is to keep the exhaust nice and quiet but also have the ability to loud. The yellow circles are the OEM exhaust valve.


M2 Hybrid exhaust, HOW IT WORKS?:
when it's in comfort/eco modem, the valves remained closed, exhaust soundwaves and gases go through the muffler.
When it's switched to Sport / Sport+ mode, the valves open up, exhaust soundwaves and gases go through the muffler and outer tips, a straight piped design just like the MPE.

Do you think this is a good design to accomplish the goal that's mentioned above? Are the valves located at the right location (Closer to the Y pipe? Closer to the tips?)

That's lots of piping not just the outside but also the inside of the canister.
The amount of efforts you will need to put into this is going to be waaaaay too much.

Do you plan to DIY?

Looks like added weight from here

No the canister is not being touched..... the M2 OEM canister stays the same. Two pipes are getting added to the pipe connected to the mid pipe.

And it's already been done at the muffler shop.
