Thank you for the kind words! The 991 has a lot of potential, and I am proud to say we have tapped into that potential with great success

LexVan the factory PSE is a great system, although for some it is lacking in the performance and sound they are looking for. For those people (and who knows perhaps yourself as well in the future), i'd like to address some of your concerns regarding going with a Fabspeed system.
Warranty: In the US you are protected under the Magnusson Moss Act stating that with aftermarket additions/replacements/upgrades the dealer has to conclusively prove that it caused the failure of the warrantied item. For instance if your water pump fails and you have an exhaust upgrade, they cannot void your warranty as it is completely unrelated. We actually have Porsche dealerships throughout the country that sell, install, and warranty our products. A lot of this trust stems from we stand behind our products with a Limited Lifetime warranty to the original owner that covers their repair/replacement from any issue stemming from our workmanship.
Fit/Finish: One of the most important parts of our R&D process of a new product is ensuring accurate fitment on every product leaving our facility. In order to accomplish this, we first map out the interference points of the factory exhaust product(s) electronically via our Romo Arm and CAD programming. We then design and build our components within those interference points to ensure an accurate, bolt-in factory replacement with no modifications necessary. After our "golden piece" is confirmed as perfect, we build a sturdy fixture around that piece and keep it forever. That way every duplicate product we make is test fitted in that fixture against that golden piece. Once confirmed in the fixture, it is sent over to our polishing room where we hand-polish our products to a mirror finish. You can see the difference between the factory PSE and full Fabspeed Valvetronic Exhaust System below.
No Drone: One of the most subjective topics, but we have yet to have any complaints of drone with our 991 X-Pipe, Maxflo Mufflers, and combination of both (Valvetronic Exhaust system). Even our full packages with Sport Headers I have had seat time in personally with a few clients of mine, and with valves closed the system is very comfortable at cruising speeds. For those especially sensitive to cabin noise, our X-Pipe (Valvetronic for PSE) with the factory side mufflers is superb on throttle and near indistinguishable from factory with valves closed at cruising speed.
Switchable: We offer a full Valvetronic Exhaust System
for those vehicles that do not come with PSE, or a Valvetonic X-Pipe
for those with PSE that would like to gain/maintain the switchable mild to wild option on their vehicles with more power/sound than what is available from factory.
Resale: Our systems are made of the finest T304L Stainless Steel that we expect to outlast the life of the car in the event you sell the vehicle. In specializing in Porsche sound and performance for near 25 years, Fabspeed is well-known and respected across the Porsche community. In the event you sell the car there would be little effect on the resale value, if not a little bit more enticing to the buyer who wants a valvetronic option on the car anyway haha.
No Power/Torque Loss: There is a fine line of backpressure in exhaust system that you can play around with to improve power overall, maximize power in some areas while not gaining as much in others, etc. This is a science we have been striving to perfect over many years, and are proud to say we very good at manipulating it to meet our goals on various products. There is no loss in power/torque with our valvetronic 991 products, in fact the gains over the factory PSE in the graph below show you how much potential there is on top of it with our Valvetronic Exhaust System...from the moment you hit the gas to redline the 991 has massive potential.
Making an educated decision is key to maximizing your driving experience, and I post this information to provide a means to do so for those interested in pursuing an option other than the factory PSE.
For those interested in any of our products or have questions on the information above, please feel free to PM, email, or call me at your convenience and I would be happy to chat with you and ensure you are set up with the proper product (or combination of products) to meet your goals.
