I took delivery of a new 435 m sport with superman combo yesterday.

I must say that I am disappointed with the exhaust note. I
had a 135 DCT and then an E92 M3. I obviously can't compare the V8 to the 435, but I remember that the 135 sounded so much louder and aggressive with a distinct blip with down changes.

Please advise whether the 435 exhaust note will change after the break-in? I can't believe that I have to spend more money to make this already expensive car sound better!

Anyway, here r some pics:

For one, there's a turbo blocking the exhaust. Can't expect anything turbocharged to sound that good from the factory.

Get a catless downpipe if you want the most cost-effective way to change the sound. You'll get some extra power as a little bonus.

But the 135 sounded great and it also had the N55. Catless will affect the warranty, or not?

No test drive?

here's a cheap & quick diy mod to leave the exhaust flap open. that should help a bit with the sound. video w/ sound in the link.

Nope...but it'll affect your smog numbers WHEN that time comes. You're a long way away from having to smog a 2014 BMW. Have fun with it. Get to modding!

I was glad to have a quieter cabin after driving my E46 M3 with AC Schnitzer exhaust for 6 years. It sounded sweet, but the drone would get to me at times.

are m performance exhausts the best out there for non-cheap sounding exhausts?

[Agamemnon]

If you want to spend $3200, the Akra has incredible sound and is a work of art! M performance is a good much less expensive alternative.

Dunno about that, but they sure look nice.

Do they still have those plugs in the trunk that you can unplug to make exhaust louder?
If so, just pull that out.

Where r these plugs? Would it be picked up when the car is serviced?

I agree...my 135i stock exhaust with DCT had an amazing sound. I definitely miss it. I guess they just tuned the 1er exhaust to be much more aggressive.

Beautiful car! Do you have the M performance exhaust option? Is it too quiet with that option?

It's on the actual exhaust. There's a little black actuator box that controls the exhaust valve. Just unplug it and plug it back in when you take it in for service.

Thanks! Nope, stock standard for now

We don't and I never heard of a SMOG test before.

I just did some searches and there are mixed reviews from the F30 drivers that did the golf tee mod or variations thereof. Apparently, it does not yield a better sound.

Has anyone done the mod to a F32

+1 that's what I do, although I have your yet to bring it in so have not plugged it back in.

I didn't even pay attention to where he was from. My bad!
