Wait till you hear it with the M2 ///M Performance Exhaust in "Track Mode" or with the Akrapovič exhaust (rumored for release late Spring).

I don't think so. The "farts" are triggered by super fast upshifts. I don't think that a person is able to shift as fast as a dual clutch with a manual single clutch.

This is nice how different everybody's taste is.

One reason why I'll order DCT instead of manual is "I LOOOVE the farts". It just sounds badass and race car like. Listen to the new RS3 when it "farts/shoots" awesome!!!!!!

This is why I f***** love dual clutch transmissions. They shift so fast that they have to fart

One thing I've always wondered is why the dual clutch on exotics, think Lambo, Ferraris, don't have that "fart".

What is the technical differences that causes these cars to make that sound when shifting fast via DCT? I'm hoping it's not emissions related compremises...

It's a new thing. Might be emissions related, but I think it's more that someone thought it was cool and the ECU is doing it on purpose.

This. Same goes for all the exhaust crackles, pseudo-misfires etc.
It's trying to infuse a bit of soul into modern engines.

More like no change from $110k with DCT.
Well Hello there sir! Long time!
Yep $110k...!

Yes it has and it sounds pretty good on that video.

I've ordered a M2 DCT LBB. Now the agonising wait!

You'll need to have these handy after you get the car. One tablet in the tank with every fill up should do the trick.

Haha Hi Fab, finally coming to the dark side then.

Great stuff mate, I'm still confused as to colour and transmission but i think LBB with DCT is the way I'll go.

Sounds good for sure, although, I must say it sounds run of the mill good. As bad as many say the F80 sounds ...it sounds like nothing else, that's for sure.

Thanks Dack.. That OEM exhaust sounds the money..
If it sounds any where close to that clip in real life, you won't need a PE..
