I modified my BMW i8 exhaust at NO COST
Here's how I modified my BMW i8 valve in order to increase the stock exhaust noise, for FREE. This doesn't result in a trouble code or check engine light, and it is very easy to reverse this and put the car back to stock. Check it out!
More exhaust sounds, here:

So far, no issues at all. No trouble codes. It sounds like Sport Mode when you apply throttle and when you're at very little throttle, it's quiet but not as quiet as it was before the flap closed. So, I'm happy with it and understand this mod is not for everyone. But for some of us, we're getting bored and want to hear more, just not Diesel-like noise from the aftermarket exhausts. It's easy to enable and put back.

If there is enough battery available to drive in reverse gear, the car will default to using the battery/electric motor. However, if you are low on battery, it may run the mid-engine and use that for reverse. Either way, you have to come out of Sport Mode to enable reverse gear.

Hi Pat
Thanks for the great idea to enhance our enjoyment of our i8s. It got me thinking about the possibility of making your modification controllable (off and on) through a mobile phone. Would you mind if I moved ahead to make a proof of concept? If that worked the next step would be to try to make a few samples and offer them to forum members at cost (I estimate less than US$30 each but until I get a working proof of concept, an rough idea of how many samples are required, etc I will not know). To conclude, I am not interested in a commercial venture (there are better ways to make money :-) ); my interest is give back to forum members from whom I have benefited so many times during my i8 journey.

That's correct. According to the wiring diagram I showed in the video, that fuse only controls this exhaust flap.

So many companies work to make exhausts sound loud and " sporty " ( what sport are they playing? lol ) but Id be the 1st in line to buy from a company that says - we will make your exhaust silent! |
