That overrun is way too much in my opinion but if you like it that's all that counts!

All of those runs were in sport plus if you put the car in comfort or regular sport it wont be near as aggressive

with those bangs you def going to kill your engine! that is way too much pressure hitting back to your turbo! that missfire dont care the way they should go... they surely leave mostly over the exhaust way but they also push backwards to the other direction! my english is not that good but maybe someone else can explain that to you. this seriously will harm your car

i have a m340i and know how the pops and bangs sound in stock. on that video above it is not the stock level.

i just listened aggain to it...
it is precisely because of those people who overdo
that tuning is being banned more and more here in europe
... enjoy that as long as you can. these kind of laws and restrictions will hit you someday too

you dont have to tune the whole car or engine for that missfire bangs!
i did a burble tune via MHD on my own car. you can set it from oem style, over soft, medium and hard! every tuner can tune your fuel like that, too.
my car is catless, too… if i set my burble tune to maximum... it is even not nearby this

I am tuned but my burbles aren't that aggressive just like you said I have catless downpipe and full awe track exhaust which makes it way louder most of these bangs aren't even at a high rpm about 3-4k rpm

M340 G20 "straight pipe" with catless downpipe

Sounds amazing OP 😁

You have the exact setup I want.

Awe Tuning Track exhaust
VRSF catless DP

However, i'm thinking about just going the cheap route and doing a muffler delete and getting quad tips fitted at my local exhaust shop.

Does anyone know if straight piping throws any lights on the dash? I know the catless DP will.

Thanks

As long as you don't mess with valves you should be good
