The Slow-Motion Exhaust Modification
I took the C2S in for that service bulletin yesterday. I noticed something interesting when the mechanic took it from the reception plaza into the shop through a short tunnel. Damn, the exhaust sounds great. One way is to install something aftermarket. Or cut something out. The other way is to drive it 28,000 miles in the cheerful rpm ranges.

Is this the fabled drive mod? With enough miles it will sound right. I bought my '08 with 46K hwy miles on it. Sounded too civilized at first and I was starting to miss the roar of my old m3 then I put 2.5k miles on her... perhaps most in the right rpm ranges as well. She growls like a big cat now and my wife complains that she's loud. Purrfect... maybe this mod is true and not just my own perception.

Must be. I was skeptical, even though I remember the old "glass pack" mufflers from the sixties showing that behavior.
This is just a great side effect of enjoying your car regularly. Put paid to any thought of my installing the sport exhaust. Hell, I'd need ear muffs.

If you are looking for a quick inexpensive exhaust mod, may I suggest the "Gundo Hack". I did this, along with a set of AWE crossover pipes and the sound is perfect; No drone, just the right amount of "growl". These mods were much cheaper that buying an aftermarket exhaust system.

Nothing like driving into the Berkeley tunnel on highway 24 at WOT with a Sharky By Pass in a GT3. Windows rolled Down of course. Best to do this after midnight so you don't have to compete with grandad in his slow *** camry jogging up the lanes.

Now at 28,000, it combines a quiet cruise with a ferocious roar on acceleration over about 4000 rpm and a burbling idle that reminds me of those hyper-expensive inboard powerboats that movie stars used to run around in on Newport Bay. Like that MGM lion that growls open each of their movies, but as if he ducked his head under a bubble bath first. Lovely.

The sound fairy struck once more today on my eager drive to work and back... or perhaps it was just the roar of envy from those who's pocket books have drained a bit for needlessly tacticool add on's and techno slush boxes around me. The snick snick shifts of her gears reminds me that she truly has the soul of a legendary sports car. Grinning all the miles home I try to contain my outward euphoria from others on the road. Who am I kidding... there is no restraint of the ying/yang resonance as her bark echoes beneath the fwy by passes for all to hear… I still can’t believe I’m driving a Porsche.

I'm no expert Gary, but have you looked inside a stock can? There is nothing inside that could change without some objectionable rattles. I was thinking that any change in sound could better be attributed to the Cats, or perhaps something in the engines program.

I'm just describing, not explaining. I might add that it isn't viewed as unusual or a problem by the dealer's service department.
