I've found that mufflers often cause the drone. I've had 2 straight piped cars that I put mufflers on and they both started droning.

We didn't on the 992 but we're about to do a series on the 718 4.0 and will be incorporating that.

Got it, anectodal listing of "loudness" from what you recall thus far?

Flat6Motorsports

They aren't really that much different in overall volume with the stock link pipes. The Tubi was the loudest, the rest were pretty similar in terms of outright volume.

This entire series is beyond helpful. It seems like Kline is the top choice in terms of OEM+ sound along with brining out my high-end notes

Thank you for the amazing work

I can confirm that the iPE has very good divergence that Jon mentions. Can slink out of my hood easily w/ valves closed and it really comes alive when open. Lots of pops/burbles and very present sound as well as head turning volume on cold start if you want it. I'm surprised its not a more popular choice particularly given price.

I'll say again that the Flat6 series is super helpful, but one must really hear the pipes in person to get an appreciation of the differences amongst choices.

Flat6Motorsports

Thanks and we appreciate the feedback. We welcome others to share their experiences in this thread too! We tried to be objective and impartial as much as possible but ultimately, sound has some subjective components to it. Our goal was to really try and cover the majority of consumer questions, use cases, etc. We're in the middle of doing a series on the 718 4.0L and we've added a decibel reader while doing the dyno runs. We're also recording decibels in the cabin at a 3K RPM hold on the dyno. If there's any other feedback on our approach or ways to make a future videos more insightful, we're all ears!

I'll raise you a "I see what you did there".

I'll add this: not only were your reviews helpful, it led to a sale for Flat6 as I felt rightly compelled to reward the effort.

+1 for Kline. Not part of Jon's great work in the exhaust series, but here's a good reference of the sound with the Kline Inconel system (and Europipe's 100cpsi cats):

What set up are you running to get that overlay and also what's your mic set up? It looks and sounds good!

I have the media mod on my GoPro, but there's still plenty of crappy audio on it.


This is my '24 GTS with a APR exhaust (stock cats).

Thanks! It was a bit of a project actually. I use Solostorm to tie everything together which handles the overlay and produces the nice video. For telemetry I have a RaceCapture Track mk/3 tapped into the passenger footwell CANBUS wires, and reverse engineered the data streams for it myself (thread) because no one had done so previously who was willing to share for free. Then for audio I've got a DJI Mic 2 (not to be confused with the OG DJI Mic with 2 Tx units; the older one has an even lower volume limit) suction cupped beneath the rear wing and plugged into the media mod. It's still a little too close and you can hear the audio clipping occasionally, but I haven't had the time or will to keep experimenting with placement to avoid peaking.

The DJI Mic is pretty plug-n-play, and wireless was an important feature for me because I'm far too lazy to run a wire along the car and tape it every time I want to record, but if that sounds like your jam there are better (read: able to handle higher volumes) mic options.

@Flat6Motorsports So money no object, which exhaust would you put on your car? Best sound, minimal drone.

What 992 model do you have @zachr

This last weekend at autocross, I ended up running a Sony Lav mic with a 10ft extension, mounted to the number plate. Probably took me about 10 minutes to wire up, but certainly questioning it doing it every time. I get clipping at WOT, so I might look at an inline controller to reduce the gain or find a better mic with higher range.
Your thread is super informative on the canbus hook ups, but something I'm going to skip for now, at least wait a while!
