m340i exhaust options
Hi all,
I have a 340i touring arriving in a couple of months. The car really impressed on the test drive but one area it could improve is the exhaust noise. The demo car I drove had a relatively low mileage, and I'd be interested to know whether it opens up a bit when run in properly? I know the OPF in these restricts the noise, but are there any options out there yet to make it a bit more lively? I'm not after anything too boy racer or anti social, just a bit more noise when in sport mode would be nice. I would also prefer to keep the standard fake exhaust tips to keep it as low key as possible visually. Is there anything out there yet that would fit this criteria? Thanks |

I think it does get a little bit louder over time but I've only covered just over 2000 miles in mine. I tend to hear more engine noise than anything else.
There are a few exhaust options out there, they're all north of £2000. ACS, Bastuck, Eisenmann and Supersprint do systems. I too would like to keep the existing exhaust trims for the understated look, the ones I just mentioned are all quad pipes so would need to take an angle grinder to a new/expensive exhaust. Stone exhaust look like they might do a system which would fit behind the current exhaust trims. Welcome to the club! |

I believe there are a few out there. Ac schnitzer rings a bell but I think it's around £2500. I think it's the only aftermarket exhaust that meets the new EU exhaust regulations.
I have also found out that bmw have a software update this year that reduces the pops/burbles. Maybe others can expand on if I'm correct as I'm not 100% sure. Can't seem to copy the YouTube link for the scnitzner zner exhaust but if you search m340i ac schnitzer. |

Remus also do an exhaust for the m340 but that is a quad pipe look as well. |

Exhaust tips £359.98 for 4 claimed compatability with M340i Have emailed them Clearly not a sound improvement option but I'm not a fan of the 'Exhaust Finishers'

According to the Milltek facebook page, they are also developing something, so at least there will options. |

It is a back box, connecting pipes and carbon tailpipes, yes.

I too am looking for more pops and bangs and little more grunt from my stock M340i exhaust. I considered the ACS quads but at over £3.5k, I think I will consider other options.
Im looking at the Milltek options. What does everyone reccomend for better sound? Not bothered about power but wouldn't mind quads. Also what implications would this have on the warranty for the vehicle? I know ACS have full warranty compliant systems, but what about Milltek? |

Anyone know what the difference is between these two systems? One requires a remap and the other doesn't:

One of them is an OPF bypass, and expect that requires a remap to configure for that bypass, whereas the other does not bypass the OPF. Thats my guess.
It would be good to hear what these sound like, as they are half the price of the ACS like for like. Plus they also offer it keeping the OEM tips for even less money, which I like to keep it low profile. |
