Another exhaust thread - but it's different, I swear
Ok so I have used the searched function. I have read and listened to most clips albeit I think for me the clips are worthless because I know in person most will sound different. Also most threads are talking about the HP gains and sound only. Not many talk about drone or "non sport" mode.
I have to pass the wife test and here is what I am looking for in order of importance. 1. Must have no drone at highway speed. 2. Must sound like stock exhaust in non sport or sport plus mode. When just crusing around with the wife with the top down we need to be able to carry on a convo or listen to music. 3. When sport plus is pressed, that is well "when the magic happens". It sounds more like a high dollar exotic. 4. Lastly, cool circular quad tips in either chrome or black but get rid of the stock tips. 5. Would like it to stay CA smog legal, I get technically no after market exhaust is supposed to pass the visual test but most will if it passes the sniffer test. I would love to be like Money and go through 5 or so exhaust's like he did on his GT3 but I neither have the money or time to do that. Does this exhaust exist out there? |
Europipe may be the best option for you. Off the top of my head I'm unaware of any aftermarket systems that utilize valve control for sound.

My first suggestion would be the Akrapovic system...
It does not have quad tips but does have carbon fiber shrouds around the tips. This video gives a pretty good representation of how much it loudens up when put in sport mode. Also, this is actually a CARB legal system. Either that or maybe the Techart system... https://www.vividracing.com/catalog/...150833988.html |
Hello Goin2drt, we recently installed an Akrapovic Exhaust to a 991 GT3 and we thought you'd might enjoy this video. Feel free to PM us and we'll be more than glad to help you out on details and pricing for this setup.

I have the FVD Brombacher sound version with 200 cell cats and my main concern was also passing the wife test.
it's very loud in sport/plus mode with lots of pops and burbles. but with her I run it in non-sport mode and even with the top down as long as the RPMs are kept reasonable (under 4k), we can have a convo or listen to music. if I really hit the gas, it gets a bit loud, but no pops or burbles (which she hates). it's definitely louder than stock even in non-sport mode, but if you don't have anything to compare it to or once you drive it like that for a while and get used to it, it's fine. and my wife has some of the most sensitive ears ever. the other option you could look at is the FVD Brombacher non-sound version, which is significantly quieter, but still should provide some increased sound in sport/plus mode. |
You sort of described a Kline 200cel system lol. I am in CA also. I Would love to offer you our 2.5 quiet system to try and extend the SamboTT By Design Guarantee. I bet by your post that you will LOVE it! We have 2 steps up in sound from there also. This is a true Jekyll Hyde set up like you want. No drone guaranteed! Wife will also love the docile sound and factory like idle. It actually sounds better than stock when cruising in normal mode. More refined, exotic and smooth. It's there but not. Sounds like it should have come on the car. The design even incorporates the same twin out set-up like factory. Tips are limited. With this system factory works and we are working on a 991 carbon tip too. CA emission is a funny game. Nothing but stock is OK. But we have options although it will run smooth and clean.
Feel free to pm or text me. Nothing to lose. I will work with you and guide you A-Z if you like and swap to whatever you decide if you aren't satisfied 100%! We can also sort a sweet package for you. Doing 3 more now so lots more feedback to come! It sounds exactly as it looks... ;) Cheers, Sam https://cimg8.ibsrv.net/gimg/www.6sp...b28c61365b.jpg https://cimg9.ibsrv.net/gimg/www.6sp...21a1636b3e.jpg |
That's funny I thought I would not get any replies because people would say I could not get all those things and I was in search of a unicorn.
So no help so far hilarious I have a vote for Europipe, two for Akro, FVB and Kline. I guess the Akro looks nice but not sure as no pics of the non diffuser yet. If it wasn't a perfect fit it would drive me nuts. |
I found this one. IPE valved exhaust. $3500 for the exhaust with cats and another $800 or so for headers which the one in the video has
|
LOL it does sound like a unicorn but I know what you mean. There are so many things to consider and the wife factor always adds to it. All of the systems mentioned are great. It's tough to choose sometimes. One thing that helps with Kline Innovation is having 3 size offerings and multiple canister styles as well as several Cat/Decat options per style. A good chat with an experienced tuner/re-seller will help weed out what may not fit you and hopefully what will fit you best.

Another exhaust thread - but it's different, I swear
Here is a clip of my Europipe in action. Best to hear on a real stereo or car stereo.
Europipe from inside the car is about as loud as stock at idle or at low RPMs. At high RPMs especially in sport and sport plus it is about 20 percent louder than stock with lots of waste gate and turbo noise and lots of popping when you back off the throttle after being on it. The tone of EP is lower pitched than stock. Also, no check engine light. EP uses stock exhaust tips so if you are looking for an exhaust with round tips, EP is not it. EP is best known for its very high build quality -- ask Porsche mechanics about it and they will confirm that. Outside the car it is a lot louder than stock but not as loud as the loudest exhausts. If you wanted very loud Tubi Catless race exhaust comes to mind. |
Thanks SDG so EP is out they don't tick number 4 on the list.
I think for now Akro is out as well. Not that I am against the single outlet I just need to see a live shot of it mounted without the diffuser so I guess I will wait, unless of course they read this post and want me to be the guinea pig by offering a killer discount hilarious I like the Kline idea and the guarantee but no tips yet for that exhaust so might need to wait. The search and ideas continue. Where is that unicorn? |

+1
The tips could be a dealbreaker for you. They are separate and can be done later. There may not be anything that matches all five criteria on one go. |

Ummm you are aware the tips can be changed and can be purchased independently if you want circular tips. EP just chooses to reuse the stock ones.
Thanks for the clarification. |
