The only way is to do a total custom work or change the muffler.

Installed the Hamann. Sounds ridiculous.
However... My butt dyno noticed a 25-50% decrease in hp and torque! When in sport mode, halfway throttle would pull hard. But now it feels like it's struggling. I put the Sport Display to track hp and torque and it "seems" less than before. I also have a Dinan Stage 1 Tune. Not sure what's going on. Any ideas or is it just in my head? |

I did not experience this however 50% reduction in HP is quite substantial. Your 500hp vehicle is now a 250hp vehicle?
In the past I've noticed that with Tunes you need approximately 200 miles of varying driving for the tune to adapt. Perhaps this may be the case? If not I would revisit the installer and investigate any possible exhaust leaks where the installation took place or further up the pipes.

after reading their response i lost complete interest in this company for a few reasons. first and foremost is their lack of knowledge of the oem exhaust. the oem exhaust on the 50i does not have a valve. secondly they're referring to audi's mmi instead of bmw's idrive and lastly anyone on here can modify and tweak the oem exhaust to achieve the same sound.

Muffler sounds are depending on the canister design, material, and packing. While the primary and secondary pipes usually just make it louder. While catless downpipe will make it more louder and raspier since no catalytic converter to dampen the sound. From material wise, the denser the material, the raspier the sound. So same muffler and design in stainless steel will sound different to the one that uses Titanium.

Now, I would gladly do it, as it will also add a bit louder sound (the thing I'm after), but I really don't want that smell - too bad we don't have sec.cats What about DP with free flowing cats - do they still have smell? |

Hi all I have a 2017 x5 50I am search of an exhaust system that I can control via a remote or app. Similar to the FI exhaust. They don’t seem to MAKE ONE FOE THE X5 50i just the x6 50i. Does anyone know if this would work?
I don’t mind going with other exhaust systems I just want to be able to control the sound with a remote or app. O prefer the deep growl and loud crack at the end! Please help! |

If you really want to turn it in/off, go with an electronic exhaust cutout with a remote. You can then have them pipe that back to your exhaust tips as well. This way you have the best of. It's worlds. I was toying with this idea, but glad I didn't because the muffler delete was perfect. |

Considering replacing the tips on my 50i through the cutting / soldering route. Happy with the stock sound but the look is pedestrian. The added performance is not as important to me.
Does anyone have the proper inlet / outlet sizing for Akra Quad Tips? I realize the Akra circular inlet doesn't fit properly with the stock rectangular inlet but would like to get the closest as possible for the mechanic to make miracles happen. P.S. would like to know if this would throw codes?

As far as I know, many went with the 2.5" inlet and dual 3.5" tips for the quad look.
