2 months on how are you finding the sound consistently with the flaps open? Any error codes or loss in fuel economy. Are you based in the UK? I assume the UK/EU version is exactly the same? Thanks |

This is still a great mod with no error codes or lights. I did not buy the M340 for its fuel economy so I can't help you there. Mine has been consistently getting around 23MPG before and after the mod......mainly city driving in Seattle's bumper to bumper traffic.

M Performance Exhaust was my fav mod on my F10 but I am very happy the way M340 as is.

Just did this mod on a 330i, no errors and quite simple as posted.
Sound is better, but can still the benefit in getting after market exhaust EDIT: Just realized this was a thread for the m340i haha. Last edited by shanknik; 03-08-2020 at 10:35 PM.. |

I unplugged mine (I have MPE) a few months ago when I installed a catted dp. No regrets.

Sweet, I have the mpe and wasn't sure if there'd really be any notable difference. I'm going to give it a go.

+1 I was planning on not unplugging it since I have MPE and I kinda of like how quiet it gets when I throw it in comfort for when I'm on the highway for a while.
Thinking about giving it a try to see if I notice any difference in sport.

Did you notice a big difference with a catted Downpipe? Which one did you go with?

I installed the VRSF catted dp. Fairly straight forward install. There are a couple videos out there. I used ramps in my garage and also put a piece of 2x8 under the passenger rear tire for a tiny bit more room. You can hear the turbo a little more and feels more responsive but I didn't do any before/after dyno pulls or 0-60 runs. ECO and Comfort are a little louder and better sounding. Sport (+) definitely sounds more amplified and you get more of the pops and gun shots.
The only thing I don't like is how loud the cold start up is. I'm prob more sensitive to that because I leave really early for work so now I start the car with the garage door down and open it after 10 secs. With all that being said, I love the mods (MPE, dp, flap unplugged). I'll just turn off the cold startup once I decide on a tune.

Anyone else having trouble getting the car to keep open the valve? I tried driving around in Sport+ and even sport and whenever I put the car in park it closes it...

Just started the car, switched into sport + and let it run idle until it opened about a minute or two later.

Edit: Finally got it to stay open, ran the car pretty hard in sport plus on the way home, kept it in sport plus and the valve was open when I parked.

A free mod for a slightly louder exhaust.
