Headers + cats 200cc
These headers / 200 cell sport cats fit:
> All the 997 2nd generation including the GTS
A catalytic converter works on the principle of creating sufficient heat within the exhaust for it to work like an oven. This sets the catalysers to work to "clean" the exhaust gases before releasing them into the environment. Since the 1st generation 987 and this 2nd generation 997, the cats have moved further up the exhaust line to have more heat. The headers and cats come in one piece per bank of 3 cylinders. So one pair per car. Originally on the 2nd generation 997 there were 2 cats on each side. Our version improves both the flow through the headers, and the performance of the cats. One of the results of this is an improvement in the sound. Of all the cars in the history of Porsche, this one makes the least sound, which is a shame as the sound it makes is fabulous. If you fit these headers/cats along with our system with valves, you will have a beautiful sound with the valves closed that will suit all driving situations. With the valves open, you will have a car with a sound verging on racing when you accelerate. This is the most beautiful of the air-cooled Porsche, but that's just my opinion! Read on and you'll see what fellow Porschists, who have already taken the plunge, have to say about this exhaust.
Our range also includes:
> A standard 400 cell catalysed version - (Reference : SCA 997-2 1 1) to order
Our exhausts all fit onto the original interfaces. By this we mean their entry, their outlet and their size are the same as those of the original part. They can therefore be fitted in replacement of the original part without requiring any modification.
These cats fit under the car between the engine and the transverse muffler. We recommend that you unplug the 2 Lambda probes before dismantling the cats, then remove them once the cats are no longer fitted to the car.
On average, it should take about 3 hours to fit them including the time taken to dismount the original exhaust. It will be faster if the exhaust you're removing is in good condition, just as it may take longer if the reverse is true.
You will need a car hoist for the job. It isn't easy to retrieve the Lambda probes so be prepared to buy new ones or have some already to hand.
Remember that the bolts must always be tightened progressively across the entire set of bolts.
To ensure that our exhausts are fitted under the best conditions, a mounting kit containing: gaskets, stainless steel bolts, stainless steel lock nuts and high temperature copper grease, is included with your exhaust.

For the first anniversary of the arrival of my 997 GTS convertible I had decided, after reading a lot of comments on various forums, to offer him the only thing he lacked: a real "voice" (the PSE having a timbre a little too slender for my taste). Barely out of the deconfinement and after exchanging with Martin Scart by email and phone (thank you for the availability and the precious advices), I therefore went to Goussainville. Arrived on site at 8:00 am, welcome by Christophe "the" editing specialist (it seems that Martin thinks he can do the whole operation blindfolded, that's to say) who patiently explained to me all that he was going to do and allowed me to take multiple photos of the operation. Comfortably installed to be able to work on my side during the intervention, I left shortly after 3:00 p.m. On the way back, already the impression of being "elsewhere", in another car. But the 35km that bring me home (suburbs, periphery and co) not being ideal to make an impression I waited the following weekend and a stroll towards the south of Ile-de-France, hood open to give me a real opinion. And indeed I can now confirm to you all that I read of positive on this exhaust of madness. A just phenomenal, captivating sound that takes you to the guts and puts a huge smile on your lips. The valve system makes it possible to reduce, of course, if necessary, but at a stable speed, with the valves open, in my opinion we can make long journeys without discomfort. So a big thank you to Martin and Christophe for their advice, their availability, their kindness and for this magical sound!

A huge thank you to Mr Martin SCART, his sales manager Mr Guillaume BEAUMONT, his team and his mecanic who fitted the exhaust and advised me to replace my original filters and tail-pipes. The result is spectacular with the valves open and discrete with the valves closed. Even with the valves closed the sound is remarkable. The combination XPIPE, VALVES, SPORT AIR FILTERS, MATT BLACK TAIL-PIPES, REMOVAL OF THE SOUND CUT-OFF AT 75 Kms/H, AND CONNECTION TO THE ORIGINAL SWITCH. I have no regrets about the cost as the result is there. Once again thank you to the SCART team. I would recommend this combination to all 997 phase II owners.

I was thrilled with my 997 GTS Cabriolet, but the original sport exhaust was a real disappointment. It was nothing like the PSE I'd had on my last 997 gen 1, which was great. I wanted an exhaust that gave me a sound, but a genuine flat 6 sound. I hesitated a while and then I went for Martin Scart's system with valves. I also liked the idea of not replacing the whole line but keeping as much as possible to the original. I just had one fear, that there would be enough sound for my taste. The result is surprising !!! I am so pleased, it's a huge bonus. Valves open the sound is fantastic, I hadn't expected that, it's well over and above my expectations. The sound is cavernous, powerful.... At full throttle its bestial and at low revs it purrs. The added benefit of the valves, which is really good, is that you can be really discreet if you need to be. The remote control is good quality. To sum up, the contact, the welcome and the workmanship were perfect
