I was torn between an exhaust with or without valves, so I called beforehand and opted for the version without valves (assuming, among other things, that they would be open all the time anyway :)). I fitted the exhaust easily and after 500 km I have no regrets, the compromise is just perfect. At a steady speed it's relatively discreet, and under acceleration / deceleration it's... a treat! Experience makes the difference, and when I had a question during installation, one phone call and I had the answer I needed in 2 minutes. I highly recommend Scart for their professionalism, availability and product quality! Read more

A handmade all-stainless-steel jewel case, for a stunning sound result on a 991! Absolutely no relation to the sport exhaust offered as an option by Porsche. We are in another world, that of the racetrack: at low revs, in the rush upward or on the way down through the revs! I kept in mind my 2 Carlsson and Brabus lines on two V8s (AMG) and never thought I would one day find MY NEW SOUND REFERENCE on a Flat Six. Practical too, the very discreet switch on the steering wheel, which lets you get back to a "stock" sound level, just a bit more metallic. Bravo to the team, and thank you for the very instructive tour of the manufacturing and fitting workshops. Thierry Read more

A big thanks to Martin and all of his team for the professionalism and kindness with which they greeted us at Goussainville. (whatsmore the price is not exorbitant compared with other brands) The sound is superb, just the right, without being excessive. He prepared two conversions: one which was fairly classic for him a 991 Targa 4S 1st generation and the second which was a first for Martin Scart a GT3RS 991 and which by the way he found fantastic (I might even have been able to sell it to him!) It's melody is a pleasure to the ear (the car radio is for sale totally useless!!!), only the air cooling system overrides this concert, notably the famous 2,7 RS. Once again a big thank you and if you would like more information about my wonderful experience with the Martin SCART team don't hesitate to get in touch. Read more

Having already equipped my 996 4S about ten years ago, it's now the turn of my 991 4S to enjoy a SCART sport exhaust (without valves) what joy exceptional melody as I accelerate and a discreet deep note at low revs. You can go for an exhaust without valves, there's no problem and it's cheaper!!!

I picked up a new 911 when I left Scart. The one thing my 911 Turbo was missing... the sound. Martin Scart grafted it on for me, a crafted sound, powerful in valves-open mode and as discreet as you like in valves-closed mode, a pure delight. A quality exhaust, a very professional team, undeniable know-how. A big thank you. Laurent G Read more

Laurent 991 Turbo I Translated from French
Hello, I would like to give you some feedback concerning the installation of a Scart exhaust on my 991 4S. My 991 had a weak spot...no sport exhaust. I know quite a bit about the original Porsche sport exhausts as I've had several 4S and GTS with the origianl sport exhaust. But this time...having taken a good look around I chose a Scart exhaust which has the reputation of being reliable and French-made. Concerning the reliability: I received the parcel on the Friday and decided to install it on the Saturday. During the installation...a doubt prevented me from going any further! I decide to try my luck, I call Guillaume on his mobile and leave a message. Within the hour Martin Scart in person called back to answer my question and resolved the problem! Not bad!!! Concerning the exhaust itself, for the first month, I was a little skeptical as I felt that the original Porsche sport exhaust had a better sound. On this point, Guillaume and Martin called me the week after the installation to find out how everything had gone (not bad either...) I shared my impression...They replied that I should be patient and wait a little for the "beast" to settle in. True enough, the beast revealed itself. What a bluff! Just crazy...It sings, it crackles, as soon as you accelerate, the sound is mind-blowing without being deafening and above all without a feeling of resonance within the car (really important). In short, a pure pleasure well over and above the original Porsche version. Just for a little anecdote, now and again I turn on the Spa Francorchamps circuit. At the most recent Porsche Days several people asked me where that beautiful sound came from...So don't hesitate, give yourself a treat, you won't regret it. Read more

This 991S is my 7th 911 and I've tested all the models from the 2,4 to the 997 GT3 including the 993 (which already had a SCART at the time...). I'd recently been disappointed by the sound of a 2nd generation 997 when I met my 991S with an enchanting PSE. The valves, well they're fun for 5 minutes, but I quickly realised that I just left them...open of course. So I installed a "Sport" exhaust without valves by SCART and there....an ecstatic sound. A deep cavernous sound but not overbearing at a steady engine speed, and then a real GT3 at high revs...what a thrill! It feels as if I've got a V8 in the back!!! Read more

Happy owner of a Porsche 991 S, and new to Porsche, I was thrilled with my vehicle. Road-holding, sensations, accelerations, equipment... perfect. I remember when on my first visit to the Porsche showroom, the salesman sat me down for at least 5 minutes in the car and almost immediately turned on the ignition so that I could hear the sound of the flat 6 echoing off the walls of the showroom. I signed. A 911 sells itself by its sound... Only several months later, I must admit to have been very frustrated by a feeling that the sound was muffled, lacking, lifeless. Wait for the tunnels and lower the windows to "hear something"... So I called Martin Scart. I came across someone who was enthusiastic, a respectful sound wizard, for beautiful machines and sensations. I left my car in his expert hands for a few hours. He gave me back a new 911 ! it's not the same car, it growls, it digs deep, roars, goes off into those high notes then comes back to the deep glouglous, and the magic of when the stick-shift automatically gives "a ittle bit of gas" still gives me a thrill. What a car! The valve system he installed also means that I don't wake up the neighbourhood, nor does it do my head in on long distances, as you can put it in "mute" mode at the flick of a button. Wow ! Martin you are a magician. Read more
