M2 Muffler mod
Has anyone done the muffler mod on the stock exhaust? I have done it on an F30 M Performance muffler. Gutted the muffler, but left a littler perforation. Sounded great. Although a little metallic with catless. Sound very nice in stock exhaust. Would anyone be interested in something like this if I were to make one?

I did it on my e92 M3 and it sounded epic. I haven't seen inside a stock M2 box yet, maybe one of the tuning houses that routinely replace these could open one up and take some pics?

E92 quad was fake, two pipes went through the box, just the tips split, the same as the M2.

This has been done. Someone on this board did it to their Alpine White, sent me pics of the process and it looks clean. His impressions on the sound were good also.

What about a bypass with an exhaust cut out valve on the right side of the rear muffler? Where the pipe attaches to the muffler. Just go pass it to the right exhaust tips? Its a mod I'm considering.
Like the markings on the picture. |

My priority will be to keep it looking oem as possible, so containing it within the muffler, cut open from the top

With the bypass behind the muffler it will look stock yet have a free flow when valve is opened. (Just added a pic to my last post) With valve closed it will act/sound exactly as stock. |
