Enjoy all the benefits of Fabspeed's world-renowned Supersport X-Pipe Exhaust System, now with dual exhaust tones at the push of a button! Unleash the full song from your 991 Turbo's flat-6 engine by removing the heavy and restrictive factory mufflers and catalytic converters.

From the factory, Porsche equipped the 991 Turbo models with an extremely powerful 3.8 L flat-6 engine setting a performance benchmark yet again for sports-cars and super-cars around the world. Despite the impressive performance, the soundtrack is decidedly lackluster without any indication as to the sheer power of the engine that fuels the fire. The exhaust note is far too sedate to be representative of a proper sports car. It was our mission to develop an exhaust system that was capable of retaining a valved system for the ultimate balance between street, and track exhaust tones.

Our engineers have spent countless hours of hands on development with the Fabspeed Valvetronic Supersport X-Pipe Exhaust System to extract the absolute best of both mild and wild exhaust notes from the 991 Turbo. The results speak for themselves.

VALVES CLOSED: Enjoy our signature Supersport exhaust sound. Exhaust flow is channeled through Fabspeed's signature 63.5mm Quad-Resonated X-pipe. We engineered it specifically to smooth out exhaust pulses for a sophisticated and exotic exhaust note while being as free flowing as possible. The tone is perfect for cruising around town or long highway drives.

VALVES OPEN: At the push of a button, the valves are opened and the exhaust is free to rocket straight out from the Sport Cats with an aggressive scream. The full story of Porsche's turbocharged 3.8 L flat-6 is unleashed, along with an intoxicating barrage of crackles and pops upon deceleration and downshifting. This system truly needs to be heard and felt in person to be appreciated.

HELICAL VALVES: We use Helical Valves for their unprecedented quality - which have been proven by many OEM manufacturers such as Porsche themselves, McLaren, Ferrari, Lamborghini, and many more.
  • Increased reliability - proven in racing and high volume OEM use
  • High-temperature bearings at both ends of the butterfly spindle
  • Cast stainless steel valve body with stiffening ribs for ultimate durability


Features:
  • Fits all Porsche 991 Turbo / Turbo S twin turbo 3.8L vehicles (2013-2016)
  • Includes high performance German imported 200-cell HJS HD Sport Catalytic Converters for improved flow and exhaust sound
  • Fully controllable valved exhaust system includes a quad-resonated center x-pipe section which mitigates exhaust volume while the valves are closed. When the valves are opened, the exhaust bypasses the X-pipe for an aggressive tone. Two unique sounds; one exhaust!
  • Dramatic improvement in sports car sound and power throughout the RPM range
  • Includes Deluxe Quad Style Tips in Polished Chrome or Black Chrome finish
  • Constructed from high-quality 14-16ga C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
  • Simple bolt-on installation; no cutting or welding required
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
  • NOTE: Fabspeed’s 200-cell high-flow catalytic converters are not C.A.R.B. certified and are for Off-Road Use ONLY in the state of California.

This is a great option for tough chewers
Color: Knuckle Bone, Size: XX-Large
This is a great option for tough chewers, although if your dogs are anything like ours, there is a procedure to ANY new toy no matter how "tough". If I gave them this Nylabone and they went unsupervised day one, they would wreck it and it'd be in the trash within the hour. I say this to tell you, if you have a top 10 bite strength aggressive chewer, that you shouldn't expect a miracle. If instead, I give it, take it away when they are working it too hard or being particularly destructive, and then give it back- and do this a few times for a week or so, then they'll chew it in a less aggressive fashion- they'll enjoy it and it lasts a long time. I don't know what it is about the first few days, but when something is "new" it has to be destroyed. When it's been in the house a few days, they are rough but not as bad. Like the ones listed "virtually indestructible" will last 6 months as long as we have multiple around. It will show damage, there will be shrapnel in the carpet that will scratch up your feet, but it'll be worthy of play still. I consider 6 months in our house worthy of 5 stars. This has been true for 2 Dobermans and a German Shepherd- and all of them have proven ability to destroy these products day 1 if I don't behave appropriately on introducing the new toy. If your dog wrecks these in the first 10 minutes, I'd say you probably need to work on supervising new toy play, and taking it away when they become to aggressive. This is a training issue, it can be done!

Lasting longer than 6 months, longer than any bone to date.
Color: Mega Knot Bone, Size: X-Large
Finally a bone that has lasted longer than 6 moths so far. I know my dog is a chewer. Well worth the cost to not have to replace them as often.

Do away with vet teeth cleaning. Great product.
Color: Monster Bone, Size: XX-Large
My large dogs love these. It keeps their teeth clean and no tarter or cavities after 4 years of using. It has even helped an adopted older dog to have stronger teeth. They don't ingest anything, so safe to chew on.

Great for chewers
Color: Knuckle Bone, Size: XX-Large
I have a 13 month old 56 lb boxer/rottie mix who is a medium chewer and this bone is great for him. No splintering, doesn't make a mess, and hard enough to make him work without any danger of him breaking teeth, getting cut, or choking. We gave it to him a couple of weeks ago and based on wear I'm confident it will last him a long time (many months at least). I was a little hesitant about giving my animal a product that contained nylon, but after a scary experience giving a rawhide bone to a previous foster dog, I was told this was a much safer option and now I agree. This bone is very dense and very hard, so it makes an awful noise when my dog drops it on my hardwood floor. We are also careful to make sure he doesn't drop it on our bare toes, because that would be quite unpleasant. Be aware that the chewed edges also get really rough because of the way the bone wears, so they can become a magnet for dog hairs or fabric threads. This hasn't been a problem for us (we just encourage our pup to chew it on his bed and take it away from him when we are watching a movie so the noise isn't bothersome), but it is good to know. Update: We've had Winston for 5 months now and in that time he has gained 5 lbs of muscle. He loves his Nylabone! It is still going strong and I think he will be able to use this well through his one year adoptiversary. The only issue we have with this bone is that the edges can get sharp and sometimes will cut his mouth. He doesn't notice and just wants to keep chewing, but we usually take the bone away at that point for a bit. My boyfriend has taken the bone and used a power sander on it a few times now to remove all the sharp edges. We only have to to in once every couple of months but it makes a big difference.
