Exhaust is a disappointment compared to my X3MC
I am really surprised that the exhaust is so quiet on my 24 G87. I just heard my wife leave in the 22 x3mc and it has me thinking time for a upgrade to Papa Smurf.
How do you open the valves on the stock exhaust? Seems that most like the full Valvetronic Designs - Valved Sport Exhaust System, anything else I should look at? Thanks |

I have the Valvetronic and like it very much so I am a little biased. May also want to check out Fi. |

No, the cats are in the downpipes, so the the system doesn’t cause any CELs.
I too have the full Valvetronic system and love it. Highly recommend. |

Single or equal length midpipe + an axle back will fix the sound problem

This is of course pure perception, but my daughter's cold start on her M240 "seems" louder than my new M2. |

Big difference with the valves closed, valves opened OEM style and valves fully opened. |

I bit the bullet and ordered the active autowerke single midpipe - so dang expensive, but between a sale and discount code made it still too expensive but Yolo. I'm excited to install it, but with the holidays, I'm unsure how fast it will come.

Have a full stainless steel Valvetronic setup on my car (posted a video in that thread for those interested).
I thought the car sounded good stock in Sport+ / valves open always open… Now it sounds menacing. Best $3k ever spent. |

A simple mid pipe upgrade will change that. AA equal length mid for example. Could go all out if wanted and do down pipe and axle back as well but starting with just the mid is a big change. |
