Good evening. I’ll add my two cents here. I have a 2017 M240i 6-speed coupe, and I had my local dealer install the M-Performance muffler. What pushed me to do it was the very annoying loud buzz/rattle that my stock muffler valve was making. I considered having the exhaust valve wired permanently open, but I wanted a more aggressive sounding muffler, and after considering Dinan, Eisenmann, Akrapovic, and Remos mufflers, but opted for the BMW M-Performance instead, being I didn’t want it crazy loud. I was told by a local performance tuning shop that the sound of the M-Performance and Dinan muffler sounds very similar. Of all the cars that I’ve heard that have an M-Performance muffler installed (factory or aftermarket), the one that fits on my car is the best sounding one I’ve heard. I’m told that the brilliant B58 engine in my F22 car is the reason why it sounds much better than other BMW models. It’s worth noting that this M-Performance muffler has NO valve, so it’s always “open”. On startup it is gnarly, and if you engage sport mode or sport+ mode when driving, you get an even nastier growl, along with louder pops and burbles. Personally, I am not a fan of the pops and burbles as I prefer just a raunchier more throaty sound, akin to the sound my suped up 1970 Camero made! I’m now considering installing the Dinan mid-pipe, which deletes both resonators. Apparently, doing this mod doesn’t made the sound much louder (maybe 10% louder), but it will have an even raunchier sound, along with a lot more pops and burbles, if you like that. So, in closing, I absolutely and wholeheartedly recommend the M-Performance muffler upgrade. Mine cost me about $1,500 CAD installed. The mid-pipe mod will cost me another $1,500 installed thereabouts.

Great Video. I am getting the MPE for my M140i that comes in September. Video helps me alot. Greetings from Germany :)

Thank God someone actually made a video about this. I've been thinking about getting the MPE for a while but NOBODY could tell me if it's worth the R16,000 (here in South Africa) to fit it. Thanks for the video brother :)

I have just had a free M performance exhaust fitted today at Tring BMW in Hertfordshire, it's been fitted under warranty because I had the dreaded rattle. I have to thank Max for all his help, he is an absolute legend and genuinely loves the M lite cars. On a slightly disappointing note they haven't managed to fit it correctly in the time they had so it's going back in the morning. It's sticking out too much and for some unknown reason the centre is knocking on the heat shield but in sure it will be fine.

The sound is amazing, I just prefer the black chrome stock look.

Since having the MPE fitted on mine i drive more in comfort/DTC mode than i used to. Also driving in traction mode (DTC) there is very little fake sound and you get all the over run noises of sport especially if you manually downshift. IMO the MPE is worth it especially as it is warranty friendly.

I took my 2011 to a performance shop to dyno- the stock achaist sounds great, But it was the quietest car there that day - of younwamt some Good sound it’s way to go

Did you egt the burbles just changing the exhaust? or Remap?

Very interesting about the warranty 🤔, thanks for the information kind of made my mind up now 👍👍. Cheers

Having watched this I don’t think mpe is worth it for couple extra burbles, which I don’t really like. It is better but only slightly.

Great video, thanks!!

Mines been back to Tring BMW and they have sorted out the knock and moved it in a bit more, however it still sticks out more than any other exhaust on the market but my 7 year old thinks it looks cool. I imagine it sticks out that much because its designed to go with the M performance rear defuser and that's more chunky than the standard one. I'd be interested to know if that is the case, if not I don't really get the sticking out look, but like you I'm just happy to have it for free.

My M140i makes me feel like a child also 😆 I might just order one now . Cheers Steve

Does this sound better then the Remus ? I wanna get a better exhaust but didn't know if the warranty would be effected ?

Is it the full MPE or is it just the M-performance end muffler?

I have a late '15 M Performance exhaust on the M135i... much louder and aggressive (as far as I can tell from the this audio) - seems they really have softened it.

Is this only slipon/axleback?

I've had a look and it seems pretty easy to adjust it yourself, it looks like there's just one bolt underneath that tightens the tip to the exhaust pipe. I'm going to have a look tomorrow and if it is easy il let you know. Have you left yours as they were or have you had them re adjusted?

Cuz of this vid I wanna get the 135 even more..

Beautiful

Hi mate, I've got a M140i too and I'm thinking of fitting a MPE as well. Your video is really good, perfect editing and really good explanation! Take a look of my channel if you want! Cheers :)

Does anyone had software problem after upgande to M performance exhaust? The car is consume too much petrol, due to gear shifting too slow and low rpm power deliver is lagging? If you put half throttle while you are driving around 60km/h, you can see petrol consumption go up, but rpm and speed is not reacting. Only you hold 2500 rpm up then the car feels fine.

This is a sick car. Kept up with the M4 all day. Looking forward to the trip to Austria (via Nurburg ring / autobahn) #MPower

My m1 looks exactly like this I love it 🥰

Hi there nice car mate I looking to getting one this year. What the tax on it for a year plus what the mileage you get on a full tank. Many thanks

Is the MPE just a back box? Or is it a full system?

Doesnt has the valvule? 😵

Bottom line no its not. Its a improvement over stock, but not worth the money, I changed to remus and its allot different. But that's not to say its no good. If it was cheaper say retail price £500 then yes.

Theres enough noise in my 140I, it's usually coming from my wife gob, it would drown that batboy out all day, and the burbles and crackles and her active over run are more prevalent if we are on the way back from the curry house, you would need the sunroof cracked for a different reason then young man.

how much ? looking at a remus costing 1500 all in.

Get the fake cabin noise coded out

i think its not loud enough. If i were driving and listening to music, i wouldnt notice much if this car drive by me.

1:22 intro jeez. I’m here for the sound and review. Ain’t got time for the rubbish music and car shots.
