It's a little bit different on the 09+ cars

Even if they got the valves to open all the time, it does NOT sound like it does during cold starts; Opening the valves hardly makes a difference.

There is not much you can do on the 09+ cars to make it sound 'mean' without going to an aftermarket exhaust.

It's a shame because I think the 560 exhaust sounds great at WOT, it's just everything else that makes it sound like an Audi....And that is unacceptable!

Get a FabSpeed exhaust and be done with it!

A Damn good Audi it is!!!

After thousands of miles the stock 570 exhaust will get louder if you run it hard with the baffles bypassed. It will never be Larini loud, but it DOES make a difference below 4k, it just doesn't sound like straigh pipes on cold start.

my friend who owns a ferrari he had the same issue and did it at the dealer for less than 100$ and it did make a different.
other friend with an Austin martin did at home simply by take a ‘’fuzz’’ off also made a different
my lambo dealer would go crazy if i did that.
i have a vlantino balboni edition i am not sure if it has different exhaust than other LP but to me it sound different.

civic, camaro and mustangs get compared to Italian exotics... Ahh ok.... I guess I'm off to the Honda store.

Currently have stock 560 & 570 exhaust. They are both the identical garage. Same weight...
