New Aftermarket Exhaust For Porsche 911 GT3 Will Make Your Ears Bleed

Tuning / Comments

And it's a bargain at $14,000.

As an all-around sports car, the current Porsche 911 GT3 is about as good as it gets. We thought there was no way it could be approved, but we've been proved wrong by Dundon Motorsports' new Street Header Exhaust Power Package for the 2022 GT3.

We've not had the pleasure of driving the new GT3, but we drove its predecessor. Taking the 991 GT3's 4.0-liter naturally aspirated flat-six past 8,000 rpm is one of life's greatest pleasures. The noise reverberates through your entire body and tickles your eardrums in all the right places.

With the $13,490 Street Header Exhaust Power Package in place, the new 911 GT3 does an even better job. But don't take out word for it. Put on those earphones and watch the video posted by Vivid Racing on YouTube.

This particular system is the non-EU version, which means it's fully compliant in the USA. Porsche's stock butterfly system is retained, which means it will pass noise laws just in case you happen to come across a police officer in California.

The package eliminates the standard Otto Particulate Filter without causing havoc with the ECU. Depending on what muffler material you opt for (stainless steel, Inconel, or titanium), you can save up to 25 pounds. Other standard items include Dundon-tuned 321 stainless steel headers, advanced high-flow catalytic converters, and PVD Black or Titanium exhaust tips.

It's not all about the noise, however. Dundon Motorsports also went through the trouble of running a stock GT3 on a dyno and found that it produces 448 hp at the wheels. With the exhaust system tacked on, the figure increases to 476, which is exceptionally close to Porsche's claimed crank horsepower figure of 502 hp.

The exhaust gives the GT3 a 28-hp boost. While we haven't seen a dyno readout for the recently launched 911 GT3 RS, we know it produces 16 hp more than the standard GT3. There's a real possibility that this exhaust system may give you more power than Porsche's track-ready supercar.

But sheer horsepower is not what the GT3 is all about, as proven by its recent run at the Nurburgring.

Still, $14k is a small price for a car that sounds this good.
