There are good sounding cars and then there are loud cars. I am looking for the former and currently, even with PSE, I am not driving a very good sounding car. Volume is not the goal.

^ In your first post you specifically wanted the loudest aftermarket exhaust

So I’m confused what you want. You want to change the sound of your car?

To me, I like how the flat six sounds, I just would like to open it up a tad more.

Yes I can see why I caused confusion. In my opinion the best sounding is not usually the loudest but others disagree. I was trying to differentiate those and find what people thought was the best sounding setup. I DO want to know which is the loudest, but only because I’d avoid it.

Hey Tupper,

We have a few videos showcasing our 200cel HJS Sport Cats. Truly the best option for increased power and sound.

This is a HUGE improvement over stock which is absolutely terrible and unacceptable for a high performance sports car.

To add to this thread...

In the 992 Carreras, will a titanium exhaust sound significantly better than stainless? I know this was the common thought in the old days, but I'm really curious to see if the additional cost for titanium is really worth it on the turbocharged cars.
Yes, I know there are weight savings in there, but I want to stay on-topic and specifically talk about sound.

Thanks.

I put on a set of Soul sport cats yesterday, havent had a chance to take it out and film anything but here is a initial fire up sound and they will get even louder after they have a chance to break in others say.

Hey Jnkirk,

No, Titanium will not make a truly noticeable difference. We strictly use T304l Stainless because, through our testing, titanium is much more prone to failure after comparative heat cycling.

^ The OEM sport exhaust is definitely pretty decent. Especially as heard from the outside.

Does it sound like a V8 muscle car? No, but it's still pretty nice, especially with higher flow sport cats like the ones I have.

Before and After
Yep added Akra to my 991.1 and it just made the car. Yes it cost but it one way it was worth it...some thing here is a cost. So when I got my992; I got an Akra even before the car arrived and despite my car having PSE. Drove it for about a month then added Akrapovic Ti slip ons and haven't looked back. Great exhaust IMHO!

Yes agree it is a decent upgrade from stock from Porsche!

As drcollie points out; there are dB limits on most major road tracks as well. I know that Laguna Seca and Sears Point (or whatever they're calling Sears Point this week) have maximum dB limits that vary by the hour of the day . . . . and they're not exactly what I'd call generous dB limits.

Another reason some prefer not to inhabit the state of CA! LOL. If you ask me...its a bit much in the way of overreach by a govt entity,

Yes won't name any names but previously have seen some guys just put super LOUD exhausts in their BWMs preferably and they are just horrid. There's a way to do it right and with some class and such that doesn't take awwu from the car and/or the driving experience.

It was as if someone put an airhorn near my head and triggered it. Six hours later I'm still ringing in my left ear from that cool cat making noise in his GT4. That guys was an asshat to run pipes that loud. And FYI, you can't run on any major track in the country these days with one of these max volume rigs.

Could have been a victim of catalytic converter thieves.

Saturdays and Sundays PCH can be a veritable race track, Lambo’s and Ferrari’s and plenty of other wannabes pretending to be hero’s but just being obnoxious. It’s no wonder the police get pressured to clamp down on noisy vehicles.

To a lot of street drivers noise equals speed. So many of these aftermarket exhausts sounds like very loud flatulence. Sounds inside the cabin are very different than that heard by anyone outside the car. Porsche’s non-PSE exhaust is a wonderful piece of engineering which produces torque and horsepower at the right rpm’s for street driving.
After many years of racing, including PCA racing, I can say that big wings, big tires, big noise does not make you fast.

My current 992 C4S has the PSE, I am actually going the other way with my targa 4S build that is on its way in December, I went with the quad pipes and no PSE. I don't prefer quite (as I have a decent sounding 720s and my F12 Ferrari was magnificent from a sound perspective). I just don't think the 911 with the popping does much for me, so opted to go more the standard flat 6 old school route without the PSE.
