Very good sound. What does this exhaust look like?

Is the Resonator and factory downpipe intact?

Factory down pipe, resonator delete. When in sport mode exhaust bypasses the muffler.

How does that work? Unless MPPSK is specifically tuned for this, it doesn’t make any sense to have a muffler bypass because the ECU would have to adjust back and forth over the course of 350miles for optimal sound and performance.

Have you considered putting your resonator back on? It would tune the exhaust to sound exotic while getting rid of drone/rasp without affecting the overall volume of your exhaust.

Yes, the mppsk is tuned for it. Yes the ecu adjusts back and forth over 350 miles, just like the engine turns over and over 350 miles.

The MPPSK is cat-back from factory, OP didn't delete it himself. There is no drone with MPPSK or with resonator delete on stock exhaust (I've deleted mine).

Google mppsk and you'll see a ton of info

Wow that sound beautiful

Here interior sound for those who are interested. Figure some valet joy riding with my car can come to some use to members

Sounds good

Try the M Performance Sound Player (available for iPhone, not sure about Android). It has pre-recorded sound tracks from a variety of BMW models, including the 340i with MPPSK, and can be used to compare exhaust notes.

Play it loud with a good quality headset on. This is what sold me on the MPPSK.

Thanks for sharing the video. Great sound!

Mppsk is life changing, is there a way to post videos on here?

Sure is ... when posting scroll down to Additional Options, In the attach files option click Manage Attachments. In the window that comes up go to the Upload File from your computer section, click one of the choose file buttons and find the video on your hard disc, click upload. Sounds more complicated than it is. If your video is already on the internet somewhere you can just link to it.

I'm guessing you are trying to post with a smart phone? I'm using a PC and am not smart enough for a smart phone, perhaps someone with smart phone expertise can chime in?
